SoC

The SoC integrates different hardware components such as the CPU, GPU, memory, peripherals, interfaces, etc., as well as software for their functioning.

Qualcomm Snapdragon 400 APQ8026Process technology

Information about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU.

CPU

CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications.

ARM Cortex-A7CPU bits

The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. 64-bit CPUs provide better performance than 32-bit ones, which on their part perform better than 16-bit processors.

32 bitInstruction set

The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU’s work. Information about the set of instructions the processor can execute.

ARMv7Level 1 cache memory (L1)

The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. The L1 (level 1) cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory. In some processors the search in L1 and L2 is simultaneous.

Level 2 cache memory (L2)

The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM.

CPU cores

A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.

4CPU frequency

The frequency of the processor describes its clock rate in cycles per second. It is measured in Megahertz (MHz) or Gigahertz (GHz).

1200 MHz

(megahertz)

GPU

GPU is a graphical processing unit, which handles computation for 2D/3D graphics applications. In mobile devices GPU is usually utilized by games, UI, video playback, etc. GPU can also perform computation in applications traditionally handled by the CPU.

Qualcomm Adreno 305GPU cores

Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications.

1RAM capacity

RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted.
