Being a handheld computer, a smartphone has a CPU.


The processor directly affects all aspects of the smartphone, ranging from speed and general performance, battery life and most importantly the price of the phone. A more powerful CPU makes the phone more expensive but also increases its performance and productivity.
I keep saying, know the best phone according to your needs and demands. The needs of an avid gamer is completely different from a social media addict, a music and general video entertainment enthusiast, to a simple online reader. Their needs are different though they think the want the same thing. Its good to know which category you lie so as not to get disappointed while you buy a phone


or buy an expensive phone that you will only utilize 10% of it.
Such issues mostly depend on the phone hardware and software. In this review i will do hard ware specifically CPU. 
There are various types of CPUs. They differ in terms of manufactures eg; Qualcomm Snapdragon


, Mediatek,


samsung’s Exynos ,


huawei HiSilicon


, intel,


just to mention but a few.
Also differ in terms  of architecture used in building them, eg, most common is ARM, 32/64 bit , Krait, which is common to Snapdragon. Etc
In terms of clock speed. CPU speed is measured in Hz. It ranges from Mhz, eg 850MHz found on Samsung earliest galaxy S, to GHz like the all powerful snapdragon 805 clocked at 2.7GHz.
Also differs in terms of number of cores. With time, number of cores has increased from single core cpus found on first generation smartphone before 2010, to dual cores between 2010-2012, quad cores as from 2012 to date, hexa and octacores that are now common to date. Its worth noting that decacore(10) CPUs are on the way, spearheaded by Mediatek but are still to become a thing. The number of cores directly affects the performance, other factors held constant. Nowadays, the minimum number is quad(4) for budget and midranger devices, while hexa(6) and octacores(8) are more common in some higher midrangers and high end devices.
Multicore CPUs also differ in terms of architecture used. Ever heard of big.LITTLE?? if curious, continue reading from this link.



  1. Very informative column. I have learnt that the mininum processor for smartphones is quadcore. Guess I’ll have to sell my old LG optimus 7 after all! Ha! Anyways Big Up and Keep Up


    1. for 2012, The optimus L7 2 was the bomb! dual core CPU, it was quite capable then. But fast forward to 2015,a dual core, unless iphones’s superior A7 dual core, dual core wont handle android, its now outdated, its now time to update!
