processor is essential for a mobile to operate.
It is also called CPU - central processing unit, similar to a processor in a computer.
It processes the input and output from users, applications and other hardwares. If the processing is fast, then the mobile works fast. Improvement in technology have introduced different speedy processors that can handle multiple requests from users and programs. Multiple cores like dual core, quad core, octa core, increases the speed of mobile phone by multithreading and multitasking.
Dual core means 2 processing unit
Quad core means 4 processing unit
Octa core means 8 processing unit
Higher the core numbers, higher is the speed. The higher version of processors also contributes to the speedy operation of a mobile phone. Every year new mobile processors are improved for speedy operation.
There is also GPU - Graphics Processing Unit , which enhances the graphics display especially in games, pictures and videos. It improves the image processing. Example: Mali-T880 MP12
Three basic things to be noted down are the speed , cores and the processor model / type.
Speed: 800Mhz, 1GHz, 1.2 GHz etc. (MHz - Megahertz, GHz - Gigahertz)
Cores: Single-core, dual-core ,quad-core, octa-core, etc
Model / type: ARM11, ARM Cortex-A9, TBC, APL, A11 Bionic, , Adreno 505 GPU, Exynos 8895,
Apple Inc. has developed a range of "System on Chip" (SoC) as well as "System in Package" (SiP).
Apple comes with A, S, T and W series processors. They integrate one or more ARM-based processing cores (CPU), a graphics processing unit (GPU), cache memory and other electronics necessary to provide mobile computing functions within a single physical package
Example: A10 Fusion / Model-APL1W24 / ARMv8-A / 2.34 GHz quad-core / (Sep 2016)
S2 / Model-TBC / Dual Core / (Sep 2016)
The processor speed, the number of cores and the processor type / model are some of the important factors that contributes to the speed of a Mobile Phone. Qualcomm snapdragon is one of the best processor in Android phones.
