The processor or SoC (System on a chip) of a Smartphone can be thought of as the brain of that smartphone.

This processor contains several things. The most important of which are CPUs.

A CPU or Central Processing Unit is responsible for carrying out the tasks and managing the functions of your Smartphone computer.

Your Processor in your Smartphone may contain several CPUs.

Each of this CPUs inside the SoC are referred to as a CORE.

If a processor has:

1 CPU, it's called a Single Core processor

2 CPUs, it's called a Dual Core processor

4 CPUs, it's called a Quad Core processor

6 CPUs, it's called a Hexa Core processor

8 CPUs, it's called a Octa Core processor

10 CPUs, it's called a Deca Core processor


Types of CPUs for Smartphones (Android)

The main company that designs CPUs for all androids is called ARM.

They then sell their design to SoC retailers/manufacturers who then use the design by ARM to build their own Unique CPU.

There are two types of CPUs widely in use in the market now to build SoCs. They are:

1. The ARM cortex A50 series which are used for only light tasks such as making calls, scrolling through FB, WhatsApp chatting, reading an eBook etc.
The A50 series consists of A53, A55 and A57

The exception here is the A57 core which is a powerful core used for heavy tasks. It is the predecessor of the A70 Series. (thank you @Naijasensei)


2. The ARM cortex A70 series which are used for heavy tasks like HD gaming, Video calls, Screen casting etc.
The A70 series consists of A72, A73, A75, A76, A77

A77 is the best currently in the market.

A few questions people may want to ask...

1. Do more Cores equal a better performance?
Well yes and no.

Yes because more CPU helps share the load of processing data and outputs the results faster making apps feel smoother and run faster.

No. Because sometimes more CPU cores isn't necessarily the answer. A Quad core A76/A55 CPU set will outperform an Octa core A57 set by far.

Then there's also optimization. This is when apps and tasks are tailor made to run smoothly on CPUs. This is why a Quad core iPhone may completely destroy an Octa-core midrange android device.

This answer to this question relies on you the individual looking at the CPU spec sheet as well as clock speed.

2. If two CPU cores are compared, is the one with the faster clock speed the best?

Well yes and no again.

Yes, if the two CPUs are of the same architecture e.g A72 Vs A72. They are both equal in every way so the only way to set them apart is the clock speed.

No. If the two CPUs are of different architectures e.g A73 Vs A76. If you like, dash the A73 a clock speed of 2.5GHz, an A76 of 2.0GHz will stroll pass it on a speedtest like Usain Bolt.

For any other question, please comment and I'll answer to the best of my knowledge.

Cheers.

thanks bro. I usually thought more cores mean a better performance.

Goalnaldo:
thanks bro. I usually thought more cores mean a better performance.

Well yes and no. It's dependent on the CPU type being used in the cores.

You're welcome bro.

Osasnidas:


Gbam you nailed it.... No wonder one recently released phone was billed for 40 something k.... The fabrication of the cores by modern standard doesn't make sense

Na Olamide phone you dey talk about.

My mind made the connection just now

What a class

atheistandproud:


Thank you

These are the types of posts I want to see on the Front Page of nairaland

Nice article. I learnt.

Dual core is 2 cores
Quad core is 4 cores
Octa core is 8 cores

Ask Google

The C P U

All I have to add is...
THANK YOU !

Dual core means that the computer is using two people's manpower to the work of 1 person.

Quad-core means that 4 people are doing the work of 1 person making it to be faster.

Octa core is 8 cores means that 8 people are doing the work which one person supposed to do. Faster to finish the work.

Going for a higher core processor and a high ram will help your computer/Laptop to process information faster .


It simply means a division of labor. Using more people to do work which makes it easier and faster to finish work.

learning

Thank you for this

How about mediatek

OP smooth one here... Please shed more light on that "Snapdragon" matter again, I usually see that word when phone searching ... What is it really, is it the smartest of cameras or something(my thoughts).

Which one is Tecno and Infinix using on their latest phones?

Thanks for this knowledge.
Trolls dey run away from this kind article.

This is very insightful. Thank you for sharing.

Simple and precise write up
Ko complex rara

op, how do we know if Qualcomm SD835 ,845, 855+ or 865 has the latest and fastest processor of ARM cortex A77.

No be lie, me too present, before register will close

PrettyBunny:

Let me mark attendance.. I was present for this class

Thanks bro.

Makes me want apple devices all again.

PrettyBunny:


Let me mark attendance.. I was present for this class

Come let's do the assignment together

Informative! Nice article

I think you’re mixing things up.. The CPU contains several cores (processors) and not the Processor contains CPU, you may have to correct that. Aside that, nice article.

MATURELION:
abeg they should do and come, they're still doing it gaming consoles they can do it with mobile phones so they can knock off all these wack mtk chipset once and for all, AMD will have the upper hand here cos they're cheap but they need to work a way around heat that's the only issue I'm having with them

Not only heat bro, how about black screen where you'll have to either heat your processor for a few hours extended lifespan or changing of panel... Lol

MATURELION:
People reading this should know CPU in laptops are totally different from CPU in phones don't mind the 2.5ghz phones can't achieve those speeds in real time infact due to many things like heat, battery and size of mobile devices they run on an architecture called soc which is where ARM comes in, and they are very low powered (don't draw enough watts) to match power requirements of laptops ... just note that

Thank you because I read this having computer system in mind and couldn’t make sense from it and was about insulting him not until after reading reading it again, I found it he is focused on mobile phones. Processors in Systems is a whole different game.

Laboni:

For Smartphones, The System on a Chip is also called a processor. This is different from what you have on a PC or Mainframe.

The individual CPUs that make up the SoC are the cores.
