To determine the performance of the Iris Pro 580 integrated graphics, I took four central processors: AMD A8-7670K, AMD A10-7890K, Intel Core i5-6400 and Intel Core i5-5675C. Based on these “stones,” it is quite possible to assemble a compact desktop and even call it a “gaming” one. For example, in a building like this. In all cases, DDR3/DDR4 RAM was used, operating in dual-channel mode and operating at an effective frequency of 2400 MHz. I attach a list of games and settings. Additional screenshots - .

Heating, throttling, noise level, power consumption
First, let's study the operating features of the NUC NUC6i7KYK. When idle, the noise emitted by the mini-computer is noticeable. It’s not annoying at all, but it’s there. A sound level meter placed half a meter away from Skull Canyon recorded 36.8 dB, which is 0.8 dB higher than the indoor noise level. So, without load, the desktop runs relatively quietly. I'm quite happy with it. But in games the impeller spins up to 4400 rpm. The noise level increases to 40.3 dB. Not a record, of course, but the characteristic sh-sh-sh-rumbling noise is immediately noticeable. Finally, in LinX the turbine begins to openly howl. There's nothing you can do: the load is extremely high, and here you have four full-fledged cores and eight threads, striving to work stably at 3000 MHz. The fan spins up to 4800 rpm.
Everything flows, everything changes, but the passion for miniaturization remains constant. At first, computers were room computers because they occupied huge areas and worked at a speed slightly higher than a simple adding machine. Then they moved into the category of floor-standing ones, somewhat reminiscent in appearance of an ordinary household refrigerator. But progress did not stand still, and they quickly began to fit under regular table. They often remain in this capacity to this day. But as is usually the case, not all users dream of a large PC, because now there is a fashion for powerful laptops, since installing a box of the ATX form factor (the standard for motherboard dimensions is 305x244 mm), developed back in 1995, many people do not raise their hands. The race for miniaturization demanded new heights, and manufacturing companies responded by developing their own mini and microcomputer formats. This is how Mini-ITX, Nano-ITX, Pico-ITX and other UTX, ETX and XTX appeared. Intel also did not stand aside, producing its mini-PCs based on its own UCFF format board, measuring 4x4 inches (approximately 100x100 mm), the first models of which appeared at the beginning of this decade. These Mini PCs are called NUC (Next Unit of Computing). And if at first it was planned to use them in various digital kiosks and as a small auxiliary computer, now these kids have already begun to confidently win their place on the desks of office workers and ordinary home users. And what’s gratifying is that this impulse (or breakthrough) was picked up by some leading manufacturers of computer equipment, starting the production of mini-PCs of this form factor.
Currently, Intel has begun producing the seventh generation of these indispensable assistants. The Intel NUC 7 lineup includes more than 15 models and kits, as well as two motherboards for DIY enthusiasts. They are based on the latest generation Intel Core i3, i5, i7 processors, which incorporate all the best that is available on this moment: full support for Thunderbolt 3 technology, new Intel Iris and Iris Plus graphics, support for Intel Optane storage technology and many others technical solutions making Intel NUC mini-PCs full-fledged computers capable of replacing the usual boxes with ATX standard boards in the office and at home.
This review will look at two mini-PCs manufactured by Intel, which essentially differ only in the processor used. One of them has an Intel Core i3-7100U processor (NUC7i3BNHXF), and the second has an Intel Core i5-7260U (NUC7i5BNHXF), but both have more than just support for the modern technology storage - Optane, and installed modules, manufactured using this technology.
The mini-PC comes in a small box made in Intel's usual bluish-blue colors. On the front side there is an image of the device and a large inscription indicating that the mini-PC belongs to the Intel NUC family. The model name is indicated in the upper left corner. It is not entirely correct, since the box contains not the NUC7i5BNH, but the NUC7i5BNHXF. The situation is similar with a computer based on an i3 processor. Probably the boxes for new computers from this series are not ready yet. This will, of course, be corrected for mass sales, but in any case, you should pay attention to the sticker (in our case it is located on the bottom side of the package) where the product model, serial number, etc. necessary information, which the buyer often rarely pays attention to.
On the left side of the package it is indicated that this PC is based on an Intel Core i5 processor (or i3 for the second device); has built-in Intel Iris Plus Graphics with support for 4K resolution (in the case of the i3 processor, built-in graphics are Intel HD Graphics 620); has pre-installed Windows 10 Home OS; that PC RAM is based on 4 GB DDR4-2400 modules; that in addition to a 1 TB hard drive, it contains a 16 GB Intel Optane memory module; and also has all the necessary ports for connecting external devices.
On the back of the Intel NUC 7 packaging, the standards supported by the mini-PC are indicated and it is specifically emphasized that, unlike many similar devices, this device has a manufacturer's warranty of 3 years, which is a lot in our age of quickly becoming obsolete computer equipment.
On right side The box shows the back side of the Intel NUC 7 mini-PC, from which the buyer can estimate the number and range of connectors for connecting external devices.
The box contains both the mini-PC itself and a metal mounting panel for mounting the Intel NUC 7 to the wall (all necessary screws are included), a very good power supply from the reliable manufacturer FSP with a set of plugs for different types of connectors, and of course everything necessary instructions on use and connection. Nothing extra. Network adapter FSP065-10AABA operates in AC networks from 100 to 240 V with a frequency of 50-60 Hz and provides an output voltage of 19 V at a current of up to 3.43 A (i.e. almost 65 W). Separately, it should be said about the mounting panel for mounting the mini-PC to the wall. This makes it possible to completely free the desk from the computer by mounting it and the monitor on the wall, and connecting the keyboard and mouse via a wireless communication line. This is the future of office and home computing, and it is already knocking on the door.

Unlike the sixth generation design, new Intel NUC 7 is aimed primarily at desktop use and the power button has therefore been moved from the top to the front panel, which is illuminated by dim LEDs during operation, which only decorates this device. This front panel also houses the USB 3.0 and 3.1 connectors that many consumers will use to connect a keyboard and mouse; as well as an Audio Jack connector, which is necessary to connect a headset. In other words, all the minimum required connectors are placed on the front panel and are always within direct reach.
On the left side of the case, discreetly (though the necessary signatures are present) is an SD card reader (SDXC) and a Kensington Security Lock, which clearly indicates that this mini-PC is primarily intended for office use. This lock is not any reliable protection against targeted theft, but it often saves against “passing” theft.
The image shows the back panels of both Intel NUC 7s: the top one has an Intel Core i3 processor, and the bottom one has an Intel Core i5 processor. They are almost no different from each other. Both have connectors: for connecting power, HDMI output for connecting a monitor, RJ45 LAN for connecting to a network, two USB port 3.0. The only difference is that a PC based on Intel Core i5 has a Thuderbolt 3 port with a connector Type-C, while in its less powerful brother, a Type-C connector supporting USB 3.1/DisplayPort 1.2 is installed in its place. Therefore, the buyer of the older version should pay special attention to purchasing a cable for this connector (not included in the package), since according to the specification, the Thuderbolt 3 port supports data transfer up to 40 Gb/s, while USB 3.1 only up to 10 Gb/s. Therefore, to successfully implement all the capabilities of the device, the buyer will need to make the right choice of cable for the port he has. Above the connectors in the case of these mini-PCs there are holes for forced ventilation, but not from the entire board (they are located on both sides of the case), but exclusively from the processor.
At the bottom of the Intel NUC 7, in addition to four rubberized feet, which are necessary to ensure stability and reduce slipping when placed on a table, there are technical stickers that indicate the model, its serial number, by whom and when it was produced.
The case is not protected in any way from curious users. If you unscrew the screws that secure the rubberized feet, you immediately gain access to the installed hard drive. This will allow, if necessary, to easily and simply replace it at home. Fortunately, this does not require any serious knowledge on the part of the user.
Under the hard drive is motherboard Intel NUC 7 mini-PC has double-sided mounting and is only 4x4 inches in size. It is fixed on a metal chassis, which is inserted into the body, which allows it to be freely removed if necessary. Access to memory modules is completely free, which is convenient for replacing or expanding them. To replace or expand RAM, the Intel NUC 7 has two SO-DIMM slots, which allows you to expand it from the standard 4 to a maximum of 32 GB. Hardly anyone will dare to decide to replace the Intel Optane module made using the most modern 3D XPoint technology, which is installed in the M.2 connector and has a 2280 form factor.
The processor is located on the back of the motherboard. Depending on the model, either the latest generation Intel Core i3 or Intel Core i5 is installed, which supports all the latest technological innovations. The processor is covered with a small, but effective and at the same time quite quiet radial fan manufactured by Delta Electronics BSB05505HP-SM with a diameter of 55 mm. The cooler supports fan rotation control via PWM and in its essence is very similar to the models used in modern laptops.
Intel Optane
Intel is known for its love for various innovations, especially when it comes to SSD drives. There have been conversations about a new generation of devices for a very long time, and not so long ago the first products for the consumer market appeared under the Intel Optane brand, based on 3D XPoint technology jointly developed by Intel and Micron. This is not NAND or DRAM. Without going into details, it is distinguished from the first by higher speed and significantly increased wear resistance, and from the second by increased data storage density. One of the main advantages of 3D XPoint memory is its higher durability, which, according to experts, is about 20 times higher than that of currently produced MLC NAND flash memory chips. The only thing that has not yet allowed this technology to conquer the computer components market is the very high price, and therefore Intel currently produces only one type of modules for the consumer market with a capacity of 16 and 32 GB, designed for installation in the M2 connector (form factor 2280 ). Since the price of new types of memory is very high, Intel decided to follow the already beaten path and position the new drives not as a replacement for full-fledged SSDs, but as a kind of accelerator for the installed drive. In essence, such an SSD is a huge cache for a much slower regular hard drive or even another SSD. We saw the same approach when the first SSDs appeared - some manufacturers released hybrid solutions, combining the capabilities of HDD and SSD. Some traditional drive manufacturers have used flash memory as a cache to quickly read data. Then Intel released the Z68 chipset with support for Smart Response technology, which used the SSD as a cache for any HDD, but using the capabilities of its proprietary driver. Subsequently, HDD manufacturers, trying to catch the departing SSD train, released new SSHD disk models with recording support. Now history is repeating itself, and Intel is releasing a cache for SSD and HDD drives based on a new generation of flash memory. It is likely that in a relatively short period of time, due to the development of this technology, new Optane products will appear on the market with low production costs. As a result, such devices will be able to seriously compete with the current generation of SSDs, which in turn will displace classic HDD drives from the user segment.
IN currently For the consumer market, two models were released with a capacity of 16 GB (one 3D XPoint memory chip) and 32 GB (two 3D XPoint chips). Each model complies with the NVM Express 1.1 specification and uses only two PCI-Express lanes out of four possible. It is worth noting that the controller for Intel Optane is an internal development of the company, but perhaps we will see it in similar solutions from Micron - QuantX. According to technical specifications, the stated endurance of the models is 100 GB of recorded data every day for 5 years.
A few words about how this technology works. So, Intel Optane technology is supported on motherboards ah Intel with 200 series chipset and higher with seventh generation Intel Core processors. At the same time, UEFI Board BIOS should be updated to latest version, that is, include the UEFI driver Intel RST 15.5 and higher. Since this technology can only work through a UEFI driver, it will not work in the normal Legacy BIOS mode. Declared Windows support 10 64-bits installed driver Rapid Storage Technology version 15.5 and higher. In addition, the HDD or SSD drive that will be accelerated using Intel Optane must be partitioned under GPT and have several MB of free space for metadata storage. The Intel Optane module itself must be installed in the M.2 connector connected to the AHCI controller built into the chipset. After connecting, installing all necessary applications(this can be either a separate utility or just the RST driver) and activating the Intel Optane mode, the system will change SATA mode controller in UEFI on Optane or RST (depending on the UEFI shell), and the system will have a new combined Optane Volume array, equal in volume to the accelerated drive.
Essentially, all of these installation steps are similar to activating the Intel Smart Response feature, but the process of operating these technologies is somewhat different. It should be immediately noted that the caching technology of the 16 GB Intel Optane differs from the 32 GB version. While the former uses caching at the block access level, the older model also uses file caching in parallel, which allows you to achieve more impressive results by transferring only the most necessary files. The principle of caching itself remains the same - at the moment the Intel Optane mode is activated, the driver transfers data for loading the OS to the Optane Memory drive and places its metadata on the drives, after which the system reboots. The user will immediately notice the acceleration effect, but transferring rather than copying means that if at some point the Optane drive fails, the system will no longer be able to boot, and the data on the accelerated drive will be difficult to recover. Subsequently, the driver will monitor the most frequently loaded data and copy it to the Optane caching drive. If in the case of block access, the decision to cache a particular block occurs instantly at the time of the I/O request, then in the case of file caching, the driver intelligently manages the cached data and enters it into the cache when idle. This, for example, eliminates caching of video and other large files. In this case, the driver gives priority to data requested by random access, since sequential read operations mainly concern large files.
If we talk about testing this technology, then everything is not so clear. Synthetic tests can show completely opposite results, since caching algorithms are unpredictable. Yes, you can certainly get very high results, as in the first picture. At the same time, after a short period of time the result can be completely opposite.
Another strange thing to note is that disabling/enabling Intel Optane technology does not always work correctly. Sometimes the utility shows that the technology is inactive, although in fact the newly created unified drive is present in the system. However, all this can be attributed to crude software, since the drives themselves entered the market quite recently and have only just appeared on sale.
Since the Intel NUCs we received have 16 GB modules installed, statistics on cached data and the ability to quickly reset the cache are not available in the utility.
In conclusion, I would like to note that the release of Optane Memory is a good attempt by Intel to revive the somewhat stagnant SSD and HDD drive market. If in the future more capacious and, most importantly, affordable models appear that can be used not only as an intermediate solution for caching, but also as the main drive, then the company may be able to gain a stronger foothold in this market. On the other hand, the very strict requirements for PC hardware and software for installing this type of media negate its advantages. And the gain in caching speed is not so obvious, especially in comparison with the latest generation of high-speed SSD drives.
UEFI BIOS
The UEFI BIOS itself, used in these models, is quite functional. Of course, there are no overclocking settings here.
According to BIOS data, the idle temperature is about 44 and 53 C (Core i3-7100U and Intel Core i5-7260U, respectively), but it is possible to control the built-in fan using PWM.
There are some settings regarding power consumption, booting from storage devices, and even the IR port and TV.
Hardware filling
Intel NUC mini PCs come pre-installed Windows system 10 64-bit. In addition, on those devices that already have Intel Optane modules installed, they are activated by default; the user does not need to go through all the steps to connect them. In general, such a computer is ideal for leisurely work in the office or at home, because its characteristics are similar to modern laptops.
As mentioned earlier, the Intel NUC models we received are based on Intel Core i3-7100U and Intel Core i5-7260U processors. These processors can be found in laptops, and their performance is enough to work with modern office applications and even play some popular games. Let us remind you that processors of this family have improved power consumption without switching to a new one. technological process. Since the Intel Core i3-7100U is the youngest in the line, it has very modest power consumption, but at the same time has a good built-in graphics core - Intel HD Graphics 620. The older model of the Intel Core i5-7260U processor has a more powerful graphics core - Intel Iris Pro.
At peak load, processors heat up to 65 and 72 C, and the cooling system operates almost silently. However, the cooling system is designed for even more powerful processors, so she copes with the task perfectly.
But in fact, this is only what it seems at first glance. In reality, under prolonged stress, the cooling system of these mini-PCs does not cope with the task. Exhausting hot air towards the cables is not a very good solution. If we assume that the Intel Nuc is suspended behind the TV, then at some point the cooling system will collect so much dust that it will operate at its maximum capacity. Considering the lack of throttling in the younger model, this can lead to disastrous consequences. However, these are just assumptions; time will put everything in its place.
conclusions
In general, in terms of characteristics, the Intel NUC models we reviewed are an excellent solution for replacing an office PC. Everything is here modern interfaces, including wireless communication, good processor performance and ultra-compact design. On the other hand, such a computer is not yet able to compete in price with all-in-one computers, because often the all-in-one computer has more powerful processors, and its cost, even including the monitor, may be lower. That is why, with great care, the new generation of mini-computers can be positioned as a replacement for the traditional PC.
On the other hand, we can confidently say that the new models are a worthy successor to the Intel NUC series of compact computers. The device has a balanced set of extensions and capabilities in a very small volume. It is also so quiet that it can even be used in a children's room. Yes, since the device is very limited in size, it does not initially have the upgrade capabilities that the vast majority of PCs have. But in everyday life, at home or at work, we do not need super-super computing power or exotic capabilities that we, at best, use once a year, if ever. Therefore, such a “baby” is of significant interest to both the average user and entrepreneurs who want to have small and reliable devices in their offices.
In recent years, tablets and laptops have become increasingly popular over conventional desktop systems. But sometimes they cannot provide sufficient performance and functionality. And the PCs themselves are not mobile enough and take up too much space.
Therefore, there was a need to create computers that would be compact at the same time and, at the same time, allow the use of most functions without restrictions. A mini-computer from Intel called Next Unit of Computing () is one of these. The company really considers such systems to be the future of computers, and not at all another implementation of the concept of nettops, all-in-one PCs or anything like that.
What is NUC
NUC is essentially a type of personal computer form factor. The device is a small box-case, usually measuring 10 by 10 cm. Despite their small size, they are not at all inferior in power to most PCs. The NUC is convenient to use as a home multimedia center, for use at work and at home, and even for games. It can easily be placed next to your keyboard on your desk or attached to the back of your monitor using the included VESA mount.
Working with a mini PC will require connecting a keyboard, mouse and screen - this can be done in a matter of minutes. At the same time, prices for such devices, depending on the configuration, are quite affordable: they start from 3-4 million rubles.
What are these devices capable of?
As described above, the NUC is capable of doing everything that modern PCs can do. At the same time, the computers implement the entire line Intel processors from mobile processors Atom to professional Core i7. Intel NUC can display images on the monitor in resolutions from Full HD to 4K, depending on the power of the device. The standard NUC package includes several USB ports (version 3.0 with support for fast charging), an HDMI output for connecting a screen and transmitting audio, an input for memory cards, Wi-Fi modules and Bluetooth, audio input (7.1 support is available), and DisplayPort ports are also present, with which you can connect multiple monitors. There is also an Ethernet input, with which you can use a LAN cable to transfer data and connect to the Internet.
After connecting all the necessary components and installing the OS, the NUC works like a full-fledged personal computer. At the same time, unlike the same laptops, the mini-PC from Intel practically does not heat up. Many NUC models have a built-in ventilation system, but there are kits without a direct fan that also show excellent temperature performance under high load. And the use of such a cooling system, coupled with the use of SSD media, makes the NUC absolutely silent - the most comfortable use.
What are the benefits of using such a system?
Being quite small and quite portable, the NUC is great for those who move frequently. The device will appeal to those who like to select components individually: the kit, in fact, includes a case, motherboard and processor, RAM modules and storage are purchased separately - all this, although it requires purchase costs and time for installation, but allows you to independently select and configure device for your own needs. The NUC can be attached to the back cover of your monitor and TV - it will not make noise or overheat, and most importantly, it will take up minimal space. This is a great option for offices and home users. Development of online services and cloud technologies allows you to give up bulky computers with noisy hard drives and a bunch of fans. Based on NUC, you can also implement, for example: a solution for a conference room, a video surveillance system, an automated kiosk for retail, an information panel (for a restaurant, airport, store).
Using such a device allows you to practically get rid of such annoying and unpleasant wires: the connection to the Internet is carried out via Wi-Fi, with peripheral devices – via Bluetooth. You just need to connect the display and power. It's especially nice to note, given rising utility prices, that the Intel NUC has low level energy consumption (12 Wh) - almost 3 times less than laptops, and 20 times more economical than PCs.
What's included
Typically, in addition to the mini-PC itself, the box contains a power supply, a mounting cover and a set of bolts. For full operation of the device, you will have to purchase an additional SO-DDR RAM module and an mSATA form factor drive (or 2.5” SATA). Therefore, you won’t be able to simply unpack the device and start using it right away. The latest generation device is a black and silver parallelepiped with rounded edges. By the way, the top black cover is decorative and can be used for branding or other information or decoration: engraving, thermal printing, stickers and many other options. On the side edges there are various ports and ventilation slots. Power is connected to the NUC through a special socket located among other connectors on the rear wall of the case.
What technologies are supported by Intel NUC
The mini-PC uses its own image processing graphics system Intel® HD Graphics, which is built into the processor - thanks to it, you can easily work with photos, videos and even play on the NUC (the same World of Tanks will comfortably run in FullHD resolution). As described above, the devices have a DisplayPort input, with which you can connect up to 3 monitors simultaneously. The sound is also responsible for its own Intel system® High Definition Audio – some models are equipped with connectors for connecting speakers/microphones, some use audio transmission via HDMI. At the same time, there is also 7.1 surround sound, which is very convenient when using the NUC as a home theater.
The device works with full versions of the OS - from Windows 10 to Ubuntu and Linux. For wireless connection Wi-Fi, Bluetooth 4.1 and Intel technology® Wireless Display 6.0.
Conclusion
– high performance in a small, attractive package. If you need a small desktop system as your main PC or home theater, then the Intel NUC with the latest processor solutions is a great option. This is an ultra-convenient option for both productivity and mobile device, which is suitable for corporate solutions, retail outlets, and home. Small sizes, a minimum of wires and ease of use will allow you to find many options for using the Intel NUC.
Recent years have been fruitful for predictions about the death of desktop computers. However, in fact, it all started about 15 years ago - when there was talk that over time, laptops would push desktops into narrow niches, or even destroy them completely. Thus, there is nothing new under the sun, and it is difficult to guess where technological progress will lead everyone in a few years. After all, a lot has also been written about the “cannibalization of the laptop market” by netbooks - now there are a lot of fans for tablets, and it’s precisely netbooks that have actually died for a long time (at least in the form in which they were first presented to the mass user). One thing is for sure: we won’t be bored. And, regardless of which class of devices becomes dominant, all sorts of advances are also possible within classes. So, for example, a few years ago, monoblocks that seemed to have died long ago found a second life. And in general, a modern desktop can be very different.
What is usually included in this concept? A stationary computer that does not have its own “own” information display device. As a rule, it has rich expansion capabilities and maximum (among single-processor solutions) performance of all systems. Big, noisy and gluttonous - already as a consequence of the previous points. For many years this definition was true, but not just yesterday the integration and increase in productivity of all computer components led to a transition from quantity to quality: it turned out that not everyone needs a classic desktop. And what you need? Relatively inexpensive, compact and quiet. At the same time, it’s not a candy bar or a laptop - it’s still supposed to be used with external monitor, keyboard, mouse, etc. But internal expansion capabilities, on the contrary, ceased to be necessary - 99% of the needs of 99% of users began to be satisfied by “integrated” controllers.
So, there is a need for miniature desktop replacements. I was the first to think about this (as often happens) Apple company, and (which is also traditional for her) even somewhat underestimated the demand. Or maybe she just didn’t quite understand him: with the “live” iMac and laptops making up the lion’s share of the company’s assortment, Mac mini there was supposed to be a niche for the “cheapest Mac”, allowing the buyer to keep the old peripherals from the “weeper” and thus (relatively) inexpensively join the world of “proper computers”. And then, you see, you will grow to Power Mac, etc. Accordingly, the very first “mini”, which appeared in the mid-2000s of this century, was an iBook G4 with a weaker video part (Radeon 9200 instead of Mobility Radeon 9550) , devoid of display and battery, but “repackaged” into a compact case measuring 16.5 × 16.5 × 5 cm and weighing 1.2 kg, while the iMac has already moved to a 64-bit Power PC G5 processor, and in Power Mac could meet two of them at once. However, the Mac mini turned out to be of interest not only to “switchers”, but also to the broad masses of workers interested in a compact and relatively productive solution, and after the transfer of this line to x86 processors Core Solo and Core Duo its representatives began to be bought for use under Windows control. In general, the demand turned out to be greater than predicted, but the computer did not solve the assigned tasks, which is why later Apple cooled down greatly on it. Continuing, however, the development of the line - including in the direction of compactness: the latest generations use cases measuring 19.7 × 19.7 × 3.6, i.e. they have become slightly larger in width than the progenitor, but noticeably thinner. Moreover, this already has a built-in power supply, while the first generation (like most competitors) used an external one. And their performance is not bad: some modifications are currently equipped with Core i7-QM series processors, i.e., quad-core, eight-thread models (the only ones of their kind). However, the production volumes of these systems were and remain limited, and the company’s pricing policy is similar to the barrier: prices only start at $599 (and this is far from being in Russia).
It once seemed that the problem could be completely solved by nettops, which were supposed to cost $100-200, which is much lower than the cost of a mini. However, the first generation of this technology quickly showed that what is cheap is cheap :) The fact is that processors of the Atom line (which were mainly used there) still do not shine with performance, and the graphics system of these platforms was incapable for a long time cope not only with games (even the simplest and oldest ones), but even with video playback. In general, despite their cheapness and compactness (many models fit into cases with dimensions of 160x190x25 mm or so), these systems could not boast of versatility - even when using discrete video chips, which increased the price, but did not completely eliminate the problems due to for weaknesses central processor. New life was breathed into this market by the emergence AMD platforms Brazos: the performance is higher than that of Atom, and the video part is at a completely different level. True, this only solved the problems of playing multimedia content, and working even on the best processors of this family (such as E-450 or E2-1800) is only possible out of despair - a Celeron from five years ago is even much faster. This is not to say that this problem was unsolvable: there have always been models on the market based on Celeron, Pentium and even Core i3 laptops, sometimes equipped with discrete graphics. These were capable of solving most problems, but were expensive, and were much smaller in size than the Mac mini, and, moreover, the smallest nettops on surrogate platforms.
It is possible that these problems would have remained eternal, but... There was no happiness, but misfortune helped. Thinking about the future of the desktop market, Intel decided to pay attention to the mobile and ultramobile segments. And suddenly it turned out that there were no great joys there either: netbooks and nettops based on Atom have low performance, “regular” laptops are too large, and there is no adequate platform for tablets at all. That’s what they did, giving birth to two at once: Atom received a SoC version and migrated to entry-level tablets (as well as smartphones), and for top models it was decided to intensify the production of CULV Core models, since the development of a new technical process made it possible. It was decided to use them in light and compact ultrabooks (a restyle of “classic” laptops with reduced thickness), as well as in miniature desktop systems. Actually, another surge in the market of the latter has already begun, so in the near future we will meet with a large number of very interesting models. But our today's hero is somewhat atypical, although extremely interesting.
Actually, everyone started looking at the NUC from the very moment of its announcement. Then we studied preliminary specifications and tests. Now it turns out that manufacturers of cases of the corresponding form factor are ready to pick up the new trend. So let's see what the next generation of computers looks like from the point of view of the leader in processor manufacturing.
NUC - Next Unit of Computer
We didn’t make a reservation above - the company really considers such systems to be the future of computers, and not at all another implementation of the concept of nettops or anything similar. This is already included in the name NUC, the explanation of which is given in the subtitle. Therefore, before we climb inside the cute little box, let's see what it is in global terms.
So, the main difference between the NUC and all other systems is the strict rejection of any mechanical drives. Any. Neither optical drives (the size of which has long limited the size of nettops) nor hard drives are there and cannot be. Although it is theoretically possible to make a case that allows the installation of such, Intel is not focusing on such a development of events: the next generation computer should be small and as “semiconductor” as possible. Accordingly, an SSD in mSATA format is supposed to be used as the main (and only) drive, and a cooling system fan is allowed as the only rotating part (and some case manufacturers go even further and propose to abandon it).
But small does not mean low-performance. No Atoms - only “full-fledged” processors Core line. Over time, budget options for Pentium and Celeron will appear (UCFF board DCP847SKE with Celeron 847, potentially allowing the buyer to save about $120 when purchasing a NUC, is already available on the Intel website), but not lower, i.e. the level of performance will be noticeably higher than the nettops that were common until recently (even the Pentium 957 was already a third faster than the AMD E-350 in terms of integrated performance), however... This concerns only the processor component and performance disk system: The use of discrete graphics is not expected. As well as other expansion options: only the use of external peripherals is possible (the only free internal Mini-PCIe slot in most cases will be occupied by the adapter wireless networks), and even then in small quantities, since both currently released NUC modifications have only three USB ports. The older one, however, can work with high-speed external devices, since it is equipped with a Thunderbolt port, but the range of peripherals supporting this interface leaves much to be desired and is mainly limited to external RAID arrays. But a computer is not supposed to have outdated interfaces, and even analog audio outputs have gone under the knife.
In general, at its core, the NUC (like the Mac mini) is a laptop (or rather, an ultrabook - times are changing) platform, but in a desktop version. But the computer is compact and (potentially) could cost less than an ultrabook - there is neither a display nor a battery, which makes it similar to nettops. Moreover, the current modifications are in many ways a test of strength and a technical demonstration of the possibility of the existence of motherboards of a new format: UCFF. But both models are, at the same time, normal commercial products, i.e. you can buy and use them right now.
Design and communication with the outside world
Externally, the computer resembles the representatives of the Zotac ZBox Nano family nettops we reviewed a year ago, but smaller and more concise. In particular, if the Nano has a case height of 4.5 cm, then the NUC is closer to the Mac mini in this parameter - 3.9 cm. The “length” and “width” are generally reduced to 117 × 112 mm, which is quite a record . Although not absolute: the “mini” is equipped with a built-in power supply, so its almost “200x200” is all that will take up space on the table or behind the monitor. The NUC (like mass-produced nettops) uses an external power supply - which, however, has its advantages: if it burns out, you can simply buy a new one, rather than undertake expensive repairs. The power supply itself, by the way, was manufactured by FSP and is a typical laptop model (i.e., easily replaceable) with a voltage of 19 V and a maximum output current of 3.42 A. The total power is thus 65 W, which is excessive for this machine - it has no chance of “eating” more than 25-30 W. On the other hand, the reserve may come in handy when more powerful models appear in the family.
When viewed from the front, the device looks very simple and concise. On the top there is a power button, on the front there is a USB port. That's all. Which, in fact, is necessary and sufficient. Even more than necessary, since many models do without USB on the front, but its presence increases ease of use.
The rear surface is also not overloaded with interfaces: a power supply connector, two more USB ports, two HDMI connectors and gigabit Ethernet. Unfortunately, all three USB ports only support outdated version specifications, despite the fact that the chipset has a built-in USB 3.0 controller. The second potential limitation is the maximum resolution of the connected display device - only 1920x1200. Want more? You will have to buy an older modification of the NUC (on the D33217CK board), which, however, has its own additional disadvantages - there is no wired network, and support for “large” monitors is ensured by the fact that instead of one of the HDMIs, an exotic Thunderbolt is installed. Taking into account the current specifics and limited range of TV peripherals, there is a feeling that the older NUC is designed for use in conjunction with Apple Thunderbolt Display, so abandoning Ethernet is quite logical - the corresponding connector is in this monitor. On the other hand, it seems to us, if the owner Apple monitor(and at a price of a thousand dollars in the USA, which in Russia turns into generally one and a half thousand) will want to purchase for it small computer, then with a 90% probability it will be the Mac mini: although it is more expensive, it is more powerful than the NUC, and - most importantly! - made by Apple :) You can, however, use Thunderbolt as a Mini-DP to connect any monitor, but in this case, as mentioned above, we will be left without a wired network. And Wi-Fi is, of course, fashionable, stylish and modern... however, despite all the tricks of the developers, at the very least it can only compete with the “old” 100Base-T in terms of real speed transfer of information. And the use of wireless networks in the NUC has its own characteristics, which will be discussed below.
In general, the current NUC lineup, in our opinion, leaves much to be desired. The older model has a limited scope of application (and in general - its target audience is unclear), while in the younger one (more precisely, in the younger ones: DCP847SKE and D33217GKE are similar in peripheral capabilities) the maximum resolution of the connected image device is limited to 1920 × 1200 (1080). You can, of course, call this nit-picking, but complaints about the lack of at least one USB 3.0 port are definitely not that. For a media player, however, or a computer for the general public, the current options are also suitable, but we would like to see another NUC: with USB 3.0 and a DisplayPort connector, replacing one of the HDMIs, but retaining Ethernet. Let's hope that your wishes will be heard. Not by Intel itself - but by partners :)
Another complaint of potential users about the NUC (which appeared immediately after the first demonstrations of the computer) is the complete absence of “traditional” audio outputs (as mentioned above): both analog and digital. Sound can only be transmitted via HDMI, which is not a problem for using the NUC as an NTRS, but for desktop use you will either have to get a suitable monitor (many modern multimedia models contain a built-in DAC, so they can output sound both to their own integrated speakers and to an external acoustics connected to the audio outputs on the monitor), or external sound card, or a corresponding set of acoustics. In general, there are actually a lot of outputs, but those who want to connect old equipment to a computer are certainly not too happy with them - somehow we are all already accustomed to the fact that two-hundred-ruble speakers can be used anywhere. Nettops are no exception to their scope of application, but you can’t connect them to the NUC.
Internal filling
By unscrewing four screws, you can remove the bottom cover of the case - this simplicity is due to the fact that a considerable number of NUCs should be sold in the form of semi-finished products: for self-configuration by the user. Actually, everything that the latter can “configure” is hidden under this cover. The list is small - only four slots. Two are designed for installing RAM in the form of SO-DIMM modules. Support for dual-channel mode (absent in many nettops on the same platform) is a strong point of the NUC: it does practically nothing for the processor, but the performance of the HDG 4000, no matter how low it is in absolute numbers, is even worse in single-channel mode.
And at the top of the photo you can see the only two expansion slots: Mini-PCIe for installing half-length cards and a combined Mini-PCIe/mSATA for full-length ones. The specificity of the layout is such that they had to be placed one above the other in a “sandwich”, with the “short” one hiding under the “long” one. In practice, this leads to serious consequences, which we will talk about later - when we touch on cooling issues. For now, we just note that the “canonically correct” scheme for using slots is to install mSATA SSD and a Wi-Fi adapter, the latter of which also has a pair of antennas (for two communication bands).
The antennas themselves are built into the top cover, which is quite logical.
All the interesting things are concentrated on the top part of the motherboard, which can only be reached by completely pulling the board out of the case. Most of it, however, is covered by the cooling system casing, so without dismantling the latter you can have fun searching for familiar chips: Intel 82579V (a gigabit network controller, now popular among all motherboard manufacturers) and Nuvoton NPCE791C (hardware monitoring controller). Do you feel like something is missing? Yes - audio codec on board there is no. That is, the refusal to use audio outputs is not the tyranny of the manufacturer, but a very clear policy, supported by the elemental base. In fact, this is the end of a long process that started back in 1997, when the AC97 standard clearly separated the analog and digital parts of audio devices. Why did you have to wait so long? In 2004, AC97 was replaced by a new standard - Intel High Definition Audio, but it immediately became clear that there were simply no standard digital outputs suitable for realizing all its capabilities for high-quality multi-channel sound on the market. Accordingly, audio codecs have become standard equipment for motherboards for a long time. However, HDMI is now actively used, where everything you need is there, so the analog part, in fact, has become a rudiment of the era - you can do without it. This is what Intel decided to do when creating the next generation computer.
And here's a close-up of what's hidden under the cooling system. Pay attention to the sizes of the chips (after all, production technology is extremely important): the processor is on the left, and the chipset is on the right; their crystals are comparable in size, but not in complexity. By the way, the chipset used is QS77, which supports all the “goodies” of business platforms (up to VT-d, vPro, etc.), which, alas, are incompatible with the Core i3-3217U processor used. Note, by the way, that in the i5 family not all models of the U and Y lines support necessary technologies, however, they still exist - here is another way further development NUC, after which the “box” will be able to interest corporate users. And enthusiasts can also be interested in a remotely controlled HTPC, for which everything is ready - only another processor needs to be soldered (which, by the way, according to the information we have, is part of the company's plans).
Temperature
As soon as the first copies of the NUC reached the testers, a small scandal immediately broke out: it was overheating, they say. In the best traditions of the genre, we have two news for you - good and bad.
Let's start with the good one: standard system There is more than enough cooling for the processor. The device performed well in all our tests (including rendering or games where the video core is actively used) regardless of the fan operating mode. The automatic mode selected by default is almost silent, but we only managed to “warm up” the processor in it to 71 degrees, which can be considered absolutely cold: the limit for this model is 105 degrees. Just for fun, we also tested the maximum rotation speed - in this case the noise emitted is already very noticeable (which is understandable - just look at the size of the fan in the photo above), however, regardless of the load, the processor temperature is still the same 41 degrees as at relative rest. Accordingly, you can either not touch the standard settings at all (they are quite suitable for the needs of practical use), or (if you want to tweak something) look for a compromise between noise and processor temperature.
As for overheating of other components, it is quite possible with this design, and this is bad news. The fact is that SSD and wifi adapter, as mentioned above, are located on the other side of the motherboard, and this compartment is not ventilated in any way in the original design. And the situation is aggravated by the fact that for compactness the slots had to be placed in a “sandwich”, and the longer SSD completely covers network card. Accordingly, when actively transferring data over the network, its chip may overheat, which is what colleagues experienced when trying to transfer a 5 GB file. Whether this problem can be solved by selecting some low-power adapters is still unknown. Similarly, the capabilities of “alternative” UCFF cases announced by many manufacturers need to be tested. However, it also requires reproducibility of the situation in situations closer to reality. Obviously, when using a wired connection (which has virtually no alternative if you need to actively exchange information: instead of waiting for a file to be transferred via Wi-Fi, you can transfer it faster to a flash drive) there will be no problems at all. Although, of course, I would like them not to arise in other situations.
Performance
As mentioned above, we ran a full set of platform performance tests on full version methods, equipping the device with two Kingston KVR1333D3S9/2G memory modules (total capacity of 4 GB) and a 256 GB Crucial m4 SSD drive. However, so far the results have nothing to compare with (all previously tested compact systems have noticeably lower performance), so we will postpone their publication a little and devote a separate material to it. But, in principle, no discoveries were made during the testing process: the Core i3-3217U is, of course, much faster than nettop and netbook platforms, but this is one of the lowest processors in the line, the frequency of which is almost half that of the desktop Core i3. Is that the graphics part is more powerful than most desktop models (not only Core i3, but also Core i5), but there is nothing unexpected for us in the performance of the HDG 4000: this graphics core is not a full-fledged gaming solution, but with all other tasks copes well. Yes, and attempts to play will be about twice as successful as in the case of the AMD Brazos platform, which has long been the leader in this segment in terms of graphics, and it is unlikely that we will see boards based on the Trinity APU with a TDP of 17 or 19 W in the near future (their supplies are excessive It’s hard to name, so basically everything is bought up by laptop manufacturers).
Total
Let's start with a global question: it is now clear how to understand Intel's statement about leaving the market of motherboards for desktop computers :) Apparently, the presence of a large laboratory in Israel affected the mentality of the company, so it turned out to be a kind of “Jewish departure”: say goodbye , but stay. Because today we saw what the next generation computer should be like: minimally configurable and maximally integrated. So why spend the energy of an entire division (Desktop Motherboard Business) on developing something that other manufacturers can easily compete with, when you can master a convenient and comfortable market segment and not strain? The UCFF format will certainly be in demand, since something more compact than Mini-ITX is often needed, and most boards for nettops are not standardized at all... So other manufacturers will also join in implementing the format, but this market segment is very easy to control, since most components is purchased from Intel, and in the finished configuration the only “weak point” is the memory modules - everything else is either already installed or can be purchased from Intel, without turning to other manufacturers at all. In addition, due to the compactness of the boards themselves, there will be nothing for a particular manufacturer to stand out too much. Unless you solder Wi-Fi somewhere and install an audio codec somewhere. Or, on the contrary, you can save a lot by soldering the Celeron and one memory slot, and providing for the possibility of installing a “regular” hard drive in the case and, accordingly, a SATA connector on the board. That's all, actually - all computers in this design will be very similar to each other, and they will be purchased in regular consumer electronics stores. And most often in an already equipped form, although with the current NUC delivery options there is also a little fuss - choosing memory and SSD.
Now as for these very current options and the concept itself. I really liked the concept. Yes, the system turns out to be somewhat more expensive than a “traditional” desktop, but it is small (it is no secret that the main component of budget desktop computers is air, filling 90% of the volume of the case) and quiet. In fact, it’s even unnoticeable - you can simply screw it to a monitor or TV using the bracket included in the package (they didn’t skimp on it - unlike the cable to the power supply, which you have to purchase yourself, since sockets are different in all countries, and there are places in the box not so much). And this is far from a nettop in terms of performance, but a fairly fast computer - many still use slower ones.
But the price and performance are determined by the specific filling, but at the moment there are a number of comments about it. The main drawback of all versions is the lack of USB 3.0 ports, despite the fact that they are supported by the chipset. And the older modification has an unclear target audience - it lacks support for a wired network (which is currently the most trouble-free way to connect the NUC with outside world- don’t forget), but it is equipped with a Thunderbolt port that is not yet very relevant. That is, simply put, we would like to see at least one more configuration option external interfaces. Yes, and a little more choice in terms of the processor too - the idea with Celeron is great for budget modifications, but slightly more expensive options would be interesting: with Core i5, or even Core i7. Moreover, the prices of processors do not differ so much: the recommended price of the Core i3-3217U is $225, which supports vPro and is faster due to Turbo Boost i5-3437U - the same $225, and the even more sophisticated i7-3667U - $346, so Intel has some freedom of maneuver. It’s easy, of course, to notice that the company, in a certain sense, is still using it now, practically “giving out” the case and power supply to the user for free (just compare the cost of the NUC with the “official” prices of the processor and chipset :)), but this option is not the only possible one .
So, as with any new concept, there is still work to be done with specific implementations. However, what distinguishes NUC from so many concepts that we have seen enough of over the past years is that even in its current form it is a real commercial product (even a product line) with a very tangible market niche. In any case, there are no problems with the target audience: all those who need a relatively inexpensive but powerful (excluding 3D graphics) compact desktop computer. In addition, this, unlike mass nettops, is also a standardized platform. Of course, with different options for peripheral connectors, so the cases will not be fully compatible (this requires a larger Mini-ITX), but the number possible options limited, i.e. we will see a variety of cases for those who like to customize the “original” NUC, and versions of production systems not only from Intel, but also from the company’s partners, many of which were already announced at CES 2013.
In general, this is truly something new and original. And it can significantly change the computer market, as well as the concept of “desktop systems” itself. What cannot be ignored is our traditional award for such cases, which the company deserved without any reservations.
Good day to all. This is my first review on this site.
A little information about myself and why I decided to buy this Chinese mini PC.
I am engaged in video production. I work in Edius, Photoshop, Adobe After Effect.
Previous computer configuration:
Intel Core Duo E7500 2.93Ghz
Video card built-in
4GB memory
SATA screw
The performance of my PC is quite enough for normal work. Only one drawback of my computer - IT'S VERY NOISE. Lately this has become very annoying, so I started looking for an alternative.
There weren't many alternatives and not all of them met my criteria.
First option.
Computer from the manufacturer Apple. I tried several times to master the programs on this operating system, but it didn’t work out.
Second option.
Buy a laptop or netbook. I can't stand this form factor.
Third option.
Intel NUC, the price, in my opinion, is a little overpriced.
These were the options I had. All of them did not quite suit my small needs.
While shopping on the alliexpress website, I came across interesting aluminum mini pcs (Chinese analogue of Intel NUC). The most important thing for me about these PCs was that they did not create noise!!!
We began searching for reviews on the Internet, but, unfortunately, there were very few of them. I found only two in Russian, and even then they were not entirely informative.
Since I was not interested in the latest achievements in the computer industry, it was difficult for me to determine what the Celeron system, iCore 3,i5, etc. are today. meets my requirements. I had them very simple, the main thing was that the computer worked no slower than the old one.
I had to spend a lot of time searching for the information I needed, but I never found it.
Then I decided to focus on price. I set the price level to 250 dollars. The PC had to have 4 GB of RAM, 32 GB SSD screw. With the rest of the money, it was necessary to find a processor with a motherboard.
There were several options: Celeron 1037U, Core i5200u, Pen j2850 and others, but I chose the Core i3 4010U (4015) processor.
Several days were spent searching for the best seller and price. After corresponding with them, I chose this one (the link is at the beginning of the review), the price and responsiveness in the comments suited me.
Due to changes in customs rules in our country, the limit on one parcel without filing a declaration is 150 euros, since the cost of the Chinese miracle was higher, a small problem arose regarding the registration of the parcel. The problem was solved very simply, the seller wrote the cost of the mini PC a little less :) than it actually was.
I asked for 4 GB of Samsung memory and Win7. He sent the parcel via EMC courier service. The track number on the official website was tracked only on the third day. After 12-13 days, the track appeared on the EMC website of the city of Kharkov.
Thank you for reading this far, now let’s move on to the review of the mini PC.
I left out a few details in the text, so in addition you can look at the review at youtube channel.
The parcel contained:
White packaging box.
Aluminium case.
Computer stand.
HDMI cable
Power supply with Euro plug.
Wi-Fi antennas
Let's start with the body.
It is made of thick cast aluminum with holes on the sides and top. The case thickness is 29mm. Dimensions 197*197*29mm. Very neat and beautiful. Weighs about 1.2 kg.
Now let's go through the connectors.
2 USB 2.0 connectors
4 USB 3.0 connectors
Video outputs: HDMI, VGA
Ethernet port 1 Gbit
Audio input and output
Connectors for Wi-Fi antennas 150 Mbit (for an additional $3 the seller will make 300 Mbit)
On/off button.
Now let's look at the filling.
Motherboard with Core i3 4010U processor
RAM DDR3L 4 GB Samsung and SSD 32 GB hard drive.
Built-in video card.
Wi-Fi module
On the case cover there are holes for another SSD screw and for a special VESA mount. Using this mount, the PC can be attached to back cover monitor or to the wall.
If you ask the seller to install bluetooth 4.0, he will do it for you for free. Unfortunately, I didn’t know this and therefore I had to buy USB bluetooth for $3 to connect a mini keyboard.
After the first boot of the system, there was not as much free space as I expected. With Win7 installed by Chinese friends, there was 11.3 GB of free space. Having installed all the programs for work, there was only about 2GB left, which is very, very little. Therefore, I decided to order another ssd screw.
For people who want to buy such a PC just for the Internet and watching movies on-line, I think 11 GB is enough for normal work.
Now let's look at some screenshots of the system.
Test results.
I have never tested my own computers, so I had to take a look at what other authors were testing, and here is the result.
I've been working on this computer for more than 1.5 months. At the moment, I'm very happy with everything. It performs all the tasks that I need. As it is written on the website, the power consumption of the PC is 15 W.
Such mini computers will find their buyer. I think this is a compromise between a desktop PC and a laptop. They will be in demand both in enterprises and for people who do not need large, powerful and noisy personal computers. One of these is Ya.
For myself, I haven’t found any disadvantages in this PC yet.
The advantages are SILENCE and peace of mind (I work at night, when my family is already asleep). A small bonus is low energy consumption.
I filmed the opening of the parcel in the video below.
If you have questions or find technical inaccuracies in my review, please write them, I will try to answer them and correct errors. Thank you.
I'm planning to buy +35 Add to favorites I liked the review +23 +60
