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.

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

Apt, simple and succinct.

Kudos to you my good man!

Wow! Such information

Thanks OP

Nice article, the only thing to note is that the cortex A57 CPU is actually a high performance core and not a power efficient core. The cortex A57 is the predecessor of the cortex A72. Popular SoCs that made use of the cortex A57 cores are the Qualcomm Snapdragon 810, and the Nvidia Tegra X1. Also, another power efficient cortex core still in use today is the cortex A35.

I should probably put that in as an exception.

Thank you very much

Which question person wan ask again na?
When you don already break down the stuff like village pikin wey dey break palm kernel for back of classroom.

Octacore is having an 8man team complete a task.

Nice one
Great article

Great work Op

they are many criteria that makes a phone fast and smooth e.g
1.the type of ram used in the phone
2. The clock speed matters
3.the type of storage used in the phone like ufs 2. 0 or 3.0 and emmc 5.1and others
4 The most important thing the proccessor

nice one op.
my question 1 optimization of a smart phone or cpu is base on what particularly ,is it the os or something particulary different

was I talking to u?

leave my class. you'll fail this course

Nice 1 but let me held on the one I knw

I know that.

I'm trying to focus on the cores aspect only and explain it.

atheistandproud good job. This is what should be seen

I hope our octacore bros and sis will learn one or two things and those ones wey buy octacore too can learn.

There is a reason why they always specify the specific cortex each processor contained, it is for ur own good so that u can use ur brain.

Dont let team octacore decieve u.

OS and the apps used.

A good example is Apple

Apple tightly controls and monitors the development of the apps used for the iPhone. They'll iron out the slightest bugs and adjust the performance of the app or game till it runs smoothly on the SoC/Chipset.

If it gives the SoC headache, apple will pull it from the Apple store till its better optimized.

The OS plays a huge part as well

Ok oo.but what about all these antutuoma and geekbench and do they really matter?

If you don't have the stress to look through the CPU architecture specs then a benchmark will simply rate it's performance for you.

The issue with benchmarks sha is that it's dependent sometimes on the SoC and the phone rather than the CPU cores themselves.

Benchmarks are a very important tool for rating the performance of SoCs in a Smartphone because of the ease in which it helps gives you a quick glance of how well it performs.

Op well done

Hmm space booked

based on this bro, which will slightly or out perform each other, Redmi Note 9 pro vs MI 9t?
