A few suggestions about competition. Controversy over choice continues Intel platforms for assembling a gaming system unit from scratch. Our “Computer of the Month” section will serve as proof. With a budget of 50-60 thousand rubles, it is possible to collect gaming computer with Core i5. But which platform should you choose? On the one hand, there is a Core i5-6400 under LGA1151. On the other hand, there are plenty of Core i5-4460 for LGA1150 on sale. There are several arguments: the processors cost the same, the Haswell chip operates at a higher clock speed, and switching to Skylake will cost more. Therefore, one of the main motives for this testing was to compare the Core i5-6400 with the Core i5-4460 in all planes.

We will contrast the Core i3-6300T chip with the Core i3-4130. This is a rather old Haswell processor, released back in the third quarter of 2013, but comparable to the energy-efficient T-model in frequency.

Let's start with the RAM test. The test bench for Haswell processors used a dual-channel DDR3-1600 set with timings of 9-9-9-28. This is the RAM controller that is integrated into all Core processors fourth generation. It is not surprising that Skylake chips were noticeably faster than Haswell in the AIDA64 test, since their built-in DDR4 controller supports RAM with an effective frequency of 2133 MHz. However, in real applications As our experiment showed, there is practically no difference between DDR3-1600 and DDR4-2133. The current generation of RAM is ruined by very high latency.

Description of test systems and testing methods

The main purpose of testing is to identify the performance gains that can be obtained by overclocking non-overclocking processors. Therefore, the junior representatives in the Core i5 and i3 lines, the Core i5-6400 and i3-6100 processors, that we took for testing were tested twice: in nominal operating mode and at a frequency of 4.7 GHz, which, based on the experience gained, can be considered sufficient a typical overclocking mode for Skylake generation CPUs. In addition, a full-fledged K-series overclocker processor, Core i5-6600K, also took part in the tests. Its presence in the tests is necessary in order to evaluate whether the overclocking performance differs between processors intended and not intended for operation in emergency modes, and if so, by how much. We tested the Core i5-6600K twice: both in nominal mode and when overclocked to 4.6 GHz (this is the maximum achievable frequency for our sample with the supply voltage increased to 1.425 V).

So, overclocking, as we knew it a few years ago - before Intel began releasing specialized overclocking processors and blocking the ability to increase operating frequencies in other CPUs, is finally returning. It is difficult to say where the solution to the issue of removing the frequency lock of the base clock generator for everything actually came from. model range Skylake. Perhaps Intel's BCLK Governor protection turned out to be not so strong and fell under the pressure of developers Motherboard BIOS plat. But it is also possible that Intel itself pushed them in the right direction, because in the end everyone won: the microprocessor giant, board manufacturers, and users.

Indeed, thanks to the newly opened overclocking opportunities, buyers have new arguments in favor of switching to the LGA1151 platform. There's no doubt that this will stimulate to a certain extent sales of new processors. Along the way, board manufacturers will also receive new clients, who will certainly be able to increase model sales by Intel based Z170. Enthusiast users will not be left out either. They face not only additional scope for experimentation, but also the opportunity to derive quite obvious financial benefits. After all, now overclocking systems can be assembled from cheaper components than before.

But what makes this whole situation especially piquant is how well everything turned out for Intel. After all, the discovery of the possibility of overclocking any, including non-overclocking, LGA1151 processors could easily cause a drop in demand for flagship Skylake models. However, sales of older Skylake with officially approved overclocking are safe. The fact is that when overclocking non-K processors, a whole bunch of problems unexpectedly arise, the worst of which is a decrease in the execution speed of AVX/AVX2 instructions. As a result, performance when working with a number of programs during overclocking not only does not increase, but, on the contrary, decreases. That is, the real benefit from such overclocking can only be obtained in cases where we are talking exclusively about working in applications that do not use the modern capabilities of the processor FPU.

All this means that if we are talking about professional activity, for which the performance of the CPU operating in nominal mode is not enough, you can choose, as before, only from the Core i5-6600K or Core i7-6700K. Overclocking non-K processors is actually only suitable for playing around - in both senses of the word. On the one hand, experimenting with overclocking such processors is incredibly interesting, because this is really something new and somewhat forbidden. On the other hand, games are among those applications that AVX/AVX2 instructions (yet?) do not use.

However, even if you are only interested in games and programs where AVX/AVX2 extensions are not used and will certainly not be used, the overclocking ability that has appeared in the Skylake generation of neo-overclocking processors does not mean at all that you, figuratively speaking, will be able to rewind time and return to golden age of the Celeron 300A. In today's realities, it is impossible to increase the performance of a cheap processor to flagship level under any circumstances. After Intel divided the range of consumer processors into classes based on the number of cores and the list of supported technologies in the mid-2000s, any “inter-class struggle” was irrevocably a thing of the past. And this was clearly shown by the tests. The younger Core i3-6100 can only pretend to try to reach the performance of the initial Core i5 models when overclocked. And the younger Core i5-6400 can try to compete with the Core i5-6600K, but, naturally, it is not capable of competing with the Core i7-6700K.

Finally on Russian market started to appear budget solutions based on Intel Skylake architecture. The sixth generation Intel Core i5 and Intel Core i3 based on 14 nm are already on sale.

This is a quad-core 14 nm processor based on the Skylake architecture, capable of operating in “ socket" LGA 1151 in conjunction with dual-channel DDR4 and DDR3L RAM.

We got acquainted with one of the top solutions with an unlocked multiplier in the article about (we also talked about the key innovations and functionality of the chipset), it was the turn of the locked CPUs, especially since we were surprised by Intel suddenly offering the possibility of refusing to link the BCLK frequency to the core clock frequency , which made it possible to easily overclock processors with a locked multiplier to significant levels, but first things first.

At the time of writing this material, a second one appeared on the Internet datasheet or technical documentation With detailed information about the sixth generation of Intel processors and Intel chipset Z170 (on English language), we offer a link to the first part.

On hundreds of sheets pdf format V the smallest details schemes for interaction of new processors with components, hardware decoupling, and connections are described; Many speed characteristics are also reflected here.

There is a lot of information, the lion's share of the text will be ignored by many, a large volume of numbers is unlikely to be useful to the average user. But, despite this, in our articles we consider it obligatory to talk at least about key features new products coming out.

Under load, the Intel Core i5-6400 rarely heats up above 45 degrees, and a BOX cooler or aluminum panel is enough to remove heat turntables

It is important to remember that the Intel Z170, and with it the sixth generation of Skylake-S processors, is an evolutionary continuation of the Intel Z97 and the Haswell architecture. In general, we have already seen that there are no fundamental changes in the performance of the 2015 and 2014 solutions, even despite the support for DDR4 memory in 14 nm-based CPUs.

Another clear confirmation of the facts described above is the generally similar form factor of the stones, the ability to work with only one PCI-E x16 port at the appropriate speed (that is, with 16 lanes), as well as generally equal hardware characteristics of comparable processors of different generations.

But it's time to talk in more detail about the culprit celebrations, namely the Intel Core i5-6400 CPU. This is a quad-core 14 nm processor based on the Skylake architecture, capable of operating in socket socket LGA 1151 in conjunction with dual-channel DDR4 and DDR3L RAM (it’s better not to focus on the latter standard, because there are no sensible motherboards with DDR3L for Skylake yet, and Intel regularly talks about the numerous limitations of this format).

There is no Hyper-Threading in the Intel Core i5-6400, as in general in the entire line core ah five, but there are four physical cores to this stone more than enough. The amount of cache memory is 6 MB. Clock frequency - 2700 MHz, in mode boosta– 3300 MHz.

The power of the physical cores of the Intel Core i5-6400 is impressive. At nominal value, this processor is practically not inferior in performance to the Intel Core i5-6600K operating in normal mode.

The heat dissipation with such characteristics is only 65 W. We have repeatedly abandoned Intel's flattering words about its productive work on energy efficiency will apparently not go without praise this time too.

Under load, the Intel Core i5-6400 rarely heats up above 45 degrees, and a BOX cooler or aluminum is enough to remove heat turntables for 500 rubles with minimal speed.

The Intel Core i5-6400 has a built-in graphics core called Intel HD Graphics 530. In the article about it, we expressed disappointment at the inability to properly get to know the built-in graphics (after all, that processor had it too). The fact was due to the relative novelty and dampness architecture and motherboards based on LGA 1151, as well as the lack of necessary software even on the motherboard manufacturer’s website (in August 2015). This time we were able to properly test the graphics built into the CPU, and the drivers finally appeared.

The Intel HD Graphics 530 was a pleasant surprise. The hardware characteristics are generally similar to in numbers previous generation (maximum memory capacity, nibbled off from RAM - 1.7 GB, core frequency - 950 MHz), but performance in 3D applications has clearly increased.

For the first time we encounter processor graphics to pull games in Full HD resolution (even at medium, even close to low, picture quality settings). The evolution in this direction is really noticeable, perhaps the day will come when the low-end category in AMD and NVIDIA will be abandoned forever due to uselessness.

Intel HD Graphics 530 supports DirectX 12, OpenGL 4.4 (although these technologies are of dubious benefit to the built-in core), as well as connecting three displays and a maximum resolution of 4096x2304 pixels.

Thus Intel line Core i5 with the advent of the sixth generation becomes even more multimedia and suitable for home use, if the user’s interests include exclusively consuming high-definition video content, and not editing and processing it. In such a case, it is realistic to get by only with the processor; external graphics are actually not needed (of course, there will be exceptions in this case, and they are far from isolated).

Test bench:

The power of the physical cores of the Intel Core i5-6400 is impressive. At nominal value, this processor is practically not inferior in performance to the Intel Core i5-6600K operating in normal mode. And all competitors from previous lines of a similar class are not much worse, and not much better. The results are quite expected - this, as mentioned above, is a logical substitute (in all formats, including in terms of power) of last year’s line, the day before last And pose-before-last.

Another thing is interesting. Firstly, the rated power of the Intel Core i5-6400 is quite enough for modern games, as well as for unlocking the working potential of the most powerful video cards (confirmation of this). We included this CPU in our research article about studying gaming potential modern processors. As a result, the Intel Core i5-6400 demonstrated exactly the same fps as the overclocked Intel Core i5-6600K and even, which is formally many times more powerful and more expensive than today’s new product.

Secondly, the Intel Core i5-6400 finally made it possible to sort out the current situation with BCLK and somewhat calm down our joy, which had apparently become illusory, about the real possibility of overclocking locked processors by raising the base bus.

The experiment with BCLK was carried out on two motherboards: , which proved that it can easily operate at 150-200 MHz according to BCLK, and also on the MSI Z170A GAMING M5, which does not pulled and 110 MHz paired with a test processor (we began to blame the motherboard from MSI due to this situation, until we were convinced that the version from ASUS was also not capable light up the fire Intel Core i5-6400 up to some serious indicators).

The Intel Core i5-6400 multiplier in UEFI is limited to 31 (it’s strange how it’s possible to reach 3300 MHz in turbo mode, because our copy is simply not capable of operating at a frequency above 3100 MHz, simple math), we tried to increase the BCLK clock frequency different ways. Automatic TPU option on ASUS board The Z170-A, which seemed to work flawlessly and one hundred percent, did not help either in the first or second mode.

We even provide screenshots of all the adjustable parameters that have been changed (almost all settings, right down to the voltage level and memory subsystem options, have been switched to Extreme mode) for overclocking the Intel Core i5-6400. Nothing helped.

Voltage on the processor - 1.305 V, on the RAM - 1.350 V, additional power functions are activated, boost for digital DIGI +, total - 3180 MHz on Intel Core i5-6400, and that's it.

For the first time we encounter processor graphics, which is able to more or less to pull games in Full HD resolution.

Apparently miracles do not happen, and the adjustable BCLK bus in a wide range is available only to owners of processors with an unlocked multiplier (on the other hand, what good is this if overclocking such CPUs will still be done in a simpler and more classic way).

There is certainly hope (after all, we have not yet tested all processors from the sixth series), but it is very illusory. The format chosen by Intel many years ago appears to have persisted to this day.

As a result, the Intel Core i5-6400, like no other processor, is optimally suited to the needs for which it is aimed. This is evidenced primarily by selling price and productivity, two key factors.

Power stone quite enough for pumping the most modern single-core graphics cards, as well as for home rendering, editing and any other household work. At the same time, the processor does not heat up at all.

An additional plus is a decent internal video core, which will come in handy if you don’t want to install an external video card for one reason or another. The Intel HD Graphics 530 can handle outputting high-definition content and processing less-than-detailed 3D scenes without difficulty.

Test results for Intel Core i5-6400 processor:

An excellent semiconductor basis for assembling a mid-level PC that can solve any problem not only now, but also in the next 2-3 years is the Intel Core i5-6400 processor. This CPU was introduced last year and continues to still be relevant and provides very high level speed. Its capabilities will be discussed in detail in the future within the framework of this review material.

Niche of this silicon product

Intel's processor products are strictly divided into market segments. Entry-level products include chips from the Celeron line and more powerful products from the Pentium line. The latter have higher clock speeds and increased level 3 cache. Middle segment market is assigned to solutions based on i3. All these CPUs have exactly the same as the entry-level solutions, only 2 computing modules. But in this case, there is support for HyperTrading technology, which allows you to get 2 times more software information processing flows. For example, the Intel i3 4170 processor, like any other representative of this family, can process program code in 4 threads at once. The premium segment in this case is occupied by i5 solutions with 4 cores/6 threads and i7 already with 4 cores and 8 threads. The hero of this review belongs to the latter group. These products provide an unprecedented level of performance and allow you to solve any problem not only now, but certainly in the next 2-3 years.

Various delivery options. Their strengths and purpose

There are two configuration options for this microprocessor product. One is the OEM processor. This configuration is minimal and is aimed at large assemblers of personal computers. It includes:

The processor itself.

Branded warranty card and multilingual manual for using this microprocessor product.

Sticker for the system unit with the name of the processor family.

In this case, there can be no question of a protective box, proprietary cooling system and thermal paste. The new owner of this CPU will have to purchase these components additionally. In this design, this chip is of greatest interest to computer enthusiasts who plan to overclock their PC. This configuration will allow you to purchase an improved cooling system and thereby achieve stable operation of the system unit after overclocking. The second configuration option for this product is called in the price list as follows: “Intel Core i5-6400 BOX processor.” In addition to everything previously mentioned, it also includes a protective box for transporting the processor, a standard cooling system and, of course, thermal paste.

Processor socket. Its relevance at the moment

This processor is designed for installation in the LGA1151 socket. This computing platform was developed specifically for the 6th generation Core CPU architecture and was presented along with its first representatives in 2016. At the moment it is relevant and allows you to collect the most productive personal computers. Also, this processor socket allows you to install more recent chips of the 7th generation. According to Intel's plans, it will be possible to install 8th generation chips that have not yet been released. So this computing platform will be relevant for at least another 2 years.

Technological aspects

The hero of this review is produced using the most advanced technological process, the tolerance standards of which correspond to 14 nm. It is due to this that the products of this family can boast of very miniature sizes and impeccable energy efficiency today. In terms of layout semiconductor elements on a substrate this technology no different from the tolerance standards of 22 nm. As before, the transistors in this case are manufactured using the same TriGate three-dimensional layout technology. Therefore, there are no fundamental differences from previous generations in this regard, and the previous generation Intel i3-4170 processor, for example, has a similar three-dimensional organization of its semiconductor elements.

Cache organization

Like all of Intel's most productive semiconductor products, the hero of this review material boasts an impressively sized three-level cache. The total size of its first level is 128 KB, which are physically divided into 4 equal parts of 32 KB each. Each of these parts is aimed at interacting with a strictly defined computing core. It should also be noted that these 32 KB, in turn, are divided into 2 parts of 16 KB each. One of them can only store instructions from the processor core, and the second can store data. The total size of the second level is 1 MB. Like the first level of fast energy memory, the second level is also divided into 4 parts of 256 KB each, assigned to a specific computing resource. In this case, there is no strict division into the storage of data or instructions. The third level is common to all CPU components - its size is 6 MB.

RAM and its controller

Equipped with an integrated RAM controller (that is, this component computing system located on the silicon chip of the central processing unit). It can function in and can address up to 64GB of RAM. Also in the technical specifications is support for two main types of RAM - DDR3 & DDR4. But it is safest to use the latter type of RAM in combination with this chip. If you use DDR3 in such a PC, the RAM controller may be damaged. Further use of such a PC will be impossible.

Thermal conditions of this product

The declared thermal package for this chip is 65 W. This is a typical value for the entire family of i5 processors of this generation, and it cannot boast of anything unusual in this regard. Maximum permissible temperature for this solution is 71 0 C. In normal mode and when using standard system cooling, the temperature of this semiconductor solution does not exceed 55 0 C. Well, if you still overclock this CPU, then it is best to abandon the use of the standard cooling system and use a more advanced modification from a third-party manufacturer.

Product frequency parameters

This semiconductor product uses a technology called TurboBust to adjust frequency depending on the temperature of the semiconductor solution and the level of complexity of the software code being executed. The minimum frequency value in this case is 2.7 GHz, and the maximum is 3.3 GHz. Upgrading the processor architecture also made it possible to increase performance computer system by increasing the frequency The question of how to overclock an Intel Core i3 or even i5 processor with a locked multiplier (that is, in the designation of such processor products there is no letter “K” at the end) will be discussed in detail in the future.

Architecture

The code name of the architecture according to which the processor was developed is Skylake. This is already the 6th generation of chips from the Kor family. On program level There is no significant difference between the i3 and i5 CPUs. These central processing units look like four-block computing solutions. But at the hardware level they differ significantly. Any Intel Core i3 processor has only 2 physical cores. The CPUs of this family support NT technology, and it is its support that allows you to convert two cores into 4 logical threads at the software level.

But i5 chips (including 6400) are full-fledged 4-core solutions. And both at the program and logical level. This is what ensures a higher level of performance in the latter case. Also i5 has more high frequencies, increased cache level and support for TurboBust technology. All this adds up to most existing software allows you to even compete on equal terms in terms of performance with more expensive products of the i7 family.

Built-in graphics subsystem of the product

As expected, it is equipped. It is located on the same semiconductor chip along with the computing part. This is HD Graphics from Intel model 530. It’s worth saying right away that its computing power is certainly not enough to fully unleash the potential of this CPU. For these purposes, the PC must be equipped with discrete video card. Well, to organize an entry-level server based on this chip, its presence is more than enough. frequency range It is limited to 350 MHz - 950 MHz, and the maximum number of connected output screens is 3.

Overclocking capabilities and percentage of performance increase

Now let's figure out how to overclock an Intel Core i3/i5/i7 processor of the last two generations (that is, 6th and 7th) with a locked multiplier (the letter “K” is missing in their markings). To do this, you need to properly equip your PC:

For motherboard there must be a special version of the BIOS, in which it is possible to increase the frequency of the clock generator.

The power supply in this case must have increased power.

Also, the RAM must operate at a frequency of 3200 MHz.

How system unit, and the processor in this case are equipped with an improved, advanced cooling system.

The overclocking algorithm in such a situation is as follows:

Download alternative firmware on a thematic forum and install it in the “BIOS”.

We reduce the frequencies of all PC components, and gradually increase the frequency of the clock generator. After each such increase, we check the stability of the computer.

When a simple increase in frequency is not enough for stable operation of the computing system, we begin to gradually increase the voltage on the CPU along with the frequency. The maximum permissible values ​​in this case for voltage and frequency are, respectively, 1.4-1.425 V and 4.5-4.7 GHz (40-45% relative to the original frequency).

Semiconductor Solution Price

The powerful Intel Core i5-6400 processor may not be available. Its price is really high - 13,000-15,000 rubles. For the same money you can purchase the flagship processor solution from AMD - FX-9370. Only the difference in performance will be significant, and the second CPU in most modern games will not provide the required level of performance. Therefore, in such a situation, it seems more justified to buy a middling product from Intel than a flagship from AMD. Moreover, most modern software is optimized specifically for Intel CPUs. They now, essentially, have no equal.
