LTE is deemed to be the fourth generation (4G) of mobile communications technology. It has been developed by the 3GPP based on the GSM/EDGE and UMTS/HSPA technologies in order to increase the speed and capacity of wireless data networks. A further development of the technology is called LTE Advanced.
UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology.
GSM (Global System for Mobile Communications) was developed to replace the analog cellular network (1G), therefore it is referred to as a 2G mobile network. It has been improved with the addition of General Packet Radio Services (GPRS) and later via the Enhanced Data rates for GSM Evolution (EDGE) technology.
There are several network technologies that enhance the performance of mobile networks mainly by increased data bandwidth. Information about the communication technologies supported by the device and their respective uplink and downlink bandwidth.
Information about the operating system used by the device as well as its version.
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 615 MSM8939Process 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.
28 nm

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.
4x 1.5 GHz ARM Cortex-A53, 4x 1.0 GHz ARM Cortex-A53CPU 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.
64 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.
ARMv8Level 0 cache memory (L0)
Some processors have a level 0 cache memory, which is accessed quicker than the L1, L2, L3, and so one cache memories. Besides achieving better performance, it also consumes less power.
4 KB + 4 KB
(kilobytes)
Level 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.
16 KB + 16 KB
(kilobytes)
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.
8CPU frequency
The frequency of the processor describes its clock rate in cycles per second. It is measured in Megahertz (MHz) or Gigahertz (GHz).
1500 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 405GPU frequency
The frequency is the clock rate of the graphic processor (GPU), which is measured in Megahertz (MHz) or Gigahertz (GHz).
550 MHz
(megahertz)
RAM 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.
2 GB
(gigabytes)
RAM type
Information about the type of RAM used by the device.
LPDDR3RAM channels
Information about the number of RAM channels integrated in the SoC. More channels mean higher data transfer rates.
Single channelRAM frequency
RAM frequency relates directly to the rate of reading/writing from/in the RAM memory.
800 MHz
