| Technological process Information about technological process, on which the chip is made. Nanometers measure half the distance between elements in the processor. | 45 nm (nanometers) |
| Processor (CPU) The primary function of a mobile device's processor (CPU) is to interpret and execute instructions contained in software applications. | ARM Cortex-A5 |
| Processor size The size (in bits) of a processor is determined by the size (in bits) of the registers, address buses, and data buses. 64-bit processors have higher performance compared to 32-bit processors, which in turn are more powerful than 16-bit processors. | 32 bit |

| Level 0 cache (L0) Some processors have L0 (level 0) cache, which is faster to access than L1, L2, L3, etc. The advantage of having such memory is not only higher performance, but also reduced power consumption. | 4 kB + 4 kB (kilobytes) |
| Level 1 cache (L1) Cache memory is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache is small in size and works much faster as system memory, and other levels of cache memory. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2. | 16 kB + 16 kB (kilobytes) |
| Level 2 cache (L2) L2 (level 2) cache is slower than L1 cache, but in return it has a higher capacity, allowing it to cache more data. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in the L3 cache (if available) or in RAM memory. | 1024 kB (kilobytes) 1 MB (megabytes) |
| Number of processor cores The processor core performs program instructions. There are processors with one, two or more cores. Having more cores increases performance by allowing multiple instructions to be executed in parallel. | 2 |
| CPU clock speed The clock speed of a processor describes its speed in terms of cycles per second. It is measured in megahertz (MHz) or gigahertz (GHz). | 1200 MHz (megahertz) |
| Graphics Processing Unit (GPU) The Graphics Processing Unit (GPU) handles calculations for various 2D/3D graphics applications. IN mobile devices ah it is used most often by games, consumer interface, video applications, etc. | Qualcomm Adreno 203 |
| Volume random access memory(RAM) Random Access Memory (RAM) in use operating system and all installed applications. Data stored in RAM is lost after the device is turned off or restarted. | 1 GB (gigabytes) |
| Type of random access memory (RAM) Information about the type of random access memory (RAM) used by the device. | LPDDR2 |

In my salon cellular communications People often ask how to choose a smartphone that suits you according to the parameters, can play modern games and at the same time is not expensive. So I decided to carry out Samsung review Galaxy Core Duos i8262, which is one of the most popular smartphones of this company in this pricing policy. The phone is quite convenient, with big screen, however, there are quite a few disadvantages. Let's look at all the pros and cons of this device and also decide whether it is worth buying in 2014-2015.
First impression
The case is not the most comfortable, smooth and glossy, easily scratched. 2 micro device sim cards, below the display there is one mechanical button and two touch ones on the sides. In principle, the phone fits comfortably in the hand, the only thing is the gloss that confuses, but do not forget that in the line of smartphones Samsung Galaxy it is considered a budget option.
Equipment
- Battery (it’s better to buy an extra one if possible)
- USB cable for connecting to a PC (part of the charger)
- Wired headset
- Charger
Installed on your Samsung Galaxy Core smartphone Li-ion battery capacity of 1800 mAh. Samsung stated that the device can last 9 hours in talk mode, and 300 in standby mode. Personally, my opinion is that the battery is too small for this gadget. The device runs on Android 4.1 Jelly Bean, which increases battery consumption.
The Core i 8262 has a 2-core Cortex A5 processor. Each core has a frequency of 1.2 GHz. This is more than enough for not the most sophisticated toys and applications. No slowdowns or freezes were noticed either; the processor is quite tolerable.
Display
The screen has a diagonal of 4.3 inches, it is quite convenient to watch movies and surf the Internet. The display on the Samsung Galaxy Core i 8262 has a resolution of 480 by 800 (WVGA), and also has a depth of colors and shades of 16 million. The screen has a pretty good viewing angle and has a pleasant color rendition, but still it’s clearly not up to amoled + holds out. However, working with such a screen is quite pleasant.
Memory
RAM 1 GB, quite a decent rating today for devices in this category price segment. It claims to have 8 GB of built-in memory, but about 5 gigabytes will be available. It is expandable up to 32 GB.
The Core i8262 has two cameras, front and rear. The resolution of the main camera is 5 megapixels, which is enough to take ordinary photographs during daylight hours, there is also led flash, but in the dark you still can’t take a normal photograph. There is also auto focus and a 0.3 m pixel front camera. The front camera is certainly not very good, but it is enough for Skype.
Little things
- Accelerometer
- Digital compass
- Motion Sensor
- GPS support
- 3.5mm headphone jack
- FM radio
- Wifi 802.11 b\g\n
- Bluetooth
Minuses
- A lot of unnecessary software that cannot be removed
- Slippery back cover
- It is inconvenient to use in a case, it is large in size
- Weak camera
pros
- Cheap, reliable
- Not a bad processor
- Support for 2 SIM cards
- Good screen

Type
Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to select the phone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.
