What is the difference between Mobile CPU and GPU? | GPU vs CPU Explained 2021

GPU vs CPU: Hello friends, when you check the specifications of a smartphone, with the processor specification, we get to see about 2 words CPU and GPU, maybe you know about what is CPU and GPU? And What is the difference between Mobile CPU and GPU? But there are still many people who do not know about it. If you are one of them then this post is only for you and we will share information about GPU vs CPU here.

What is the difference between Mobile CPU and GPU? | GPU vs CPU Explained

Why is CPU and GPU given in mobile and how can we know whether the CPU or GPU of a smartphone is good or not? With this, what effect does this have on the performance of our Smartphone?

Because when we buy a smartphone, we do not have the right information about its specification, then we will buy the phone by looking at the design and camera, which can prove to be Worst for us later.

What is GPU?

The Smartphone GPU (Graphics Processing Unit) is also a part of the mobile processor and is also an important factor for any smartphone performance.


Graphics, as the name also mentions, is a specialized circuit/chip that helps buffer the frame and give the output correctly.

In today’s time, the GPU is very widely used by all types of smartphone brands so that it can give its users a better video, image, and gaming experience.

At this time, the GPU of Adreno, Mali is being used the most.

What is CPU?

We know about it and we also got information about the CPU (Central Processing Unit) with computer motherboard definition.


If we talk about the mobile CPU, then it is a chip and is part of the mobile processor. When we input mobile using Keyword, Touch, Voice here any input technology.

So the CPU helps to understand it correctly and give the right output.

There are some important factors of mobile CPU,

Clock Rate- With the help of this, the performance measurement of Smartphone CPU is done and we measure it in Hertz. The performance of a CPU that has a high clock rate is as good.

Architectures-  CPU is the second most important factor, if the architecture of a mobile CPU is based on the latest and advance technology.

So it will be energy efficient and processor heat will be less and give better performance.


We all must have got a little idea about GPU and CPU, now we will understand better that What is the difference between Mobile CPU and GPU? And this is how our smartphones work.

CPU which is the central processing unit of any smartphone or computer. It manages every single activity in the smartphone and for this it uses Major 4 Step.

  1. Reading – When a user enters an input on the smartphone, then with the help of memory, it reaches the CPU and the mobile CPU reads that input/instruction.
  2. Decoding – After reading the Instruction, the mobile CPU makes it understandable and this is called Process decoding.
  3. Execution –   After decoding the input, the central processing unit sends it to the correct component for processing.
  4. After the writing – execution process is complete, we get it according to our given input through the right answer output device.

Like if we click on the Music player app on mobile to play the song, then the input given by us goes to the CPU first.

After that the CPU reads the input to play the song given by us and forward the process to the music player and the song is played.

The GPU is a co-processor that works for the CPU and helps them perform their tasks in a fast and easy way.

If we  talk about major technical difference in GPU vs CPU Hindi , then we will see some such differences in it.

This is the brain of the mobile that processes all kinds of tasks that happen in the mobile.It performs the processing of any one specific task.
In this we get very few Cores (Up to 24).In this, we get to see many more cores from the CPU, which are in thousands.
Its cores perform sequential serial processing and only do one task at a time.It has parallel architecture cores which handle many functions at one time.

CPU Vs GPU –  Video Demo

Smartphone Without CPU or GPU

The CPU and GPU together process all the tasks of the mobile and perform in a fast manner.

At this time, both of these have been made so advance that we can complete the task related to any scientific, analytics, engineering, consumer, and enterprise applications in our mobile just like a computer.

The GPU works specifically for image and display motion. You all will know that video is a collection of images and not many, which has been tied to many frames.

The GPU helps in displaying these images in a better way and controls their motion.

If there is no GPU system in our phone, then neither an image will open correctly in our phone nor any video will play correctly.

With this, the most important thing for the game is the most important graphics.

If there is a phone that does not have a CPU system, then its condition will be the same as that of a computer monitor without a CPU system.

We cannot perform any task in the phone or say that our phone will be absolutely dead.

How to check CPU or GPU is good or not?

Every phone has both these features but in a phone it is better and in a phone it is average.

In this case, if we want to buy a Smartphone . So how do we know whether the CPU and GPU given in the phone is good or not?

There are three main parts of a phone processor.

  • Chipset: Qualcomm SDM845 Snapdragon 845 (10 nm)
  • CPU: Octa-core (4×2.8 GHz Kryo 385 Gold & 4×1.7 GHz Kryo 385 Silver, CPU Clock Speed: Up to 2.8 GHz)
  • GPU: Adreno 630

In the chip-set, we have the name of the processor manufacturing company , Series name and technology. Like here,

  • Company Name: Snapdragon
  • Series name: 845
  • Technology: 10nm (The lower the technology design, the more efficient will be the processor)

The main feature of CPU is core and clock speed,

Cores : Mobile Core features  | Computer Core features

Clock Speed: The better clock speed is in the CPU, its performance is as good as 2.8GHz clock speed is given here.

Its performance will be better than the processor with 2.3GHz clock speed of the same GPU .

There are many factors in the GPU, in which we can decide from the graphics brand, series, technology and the features given in it, how is the graphics of the phone? Like here Adreno 630 in it

  • Technology: 10nm
  • DirectX:  DirectX 12 (latest graphics API version)
  • Features: OpenGL ES 3.2, OpenCL 2.0, DirectX 12

Friends, how good design, powerful camera, and best quality display can be found in any phone. But if the Phone GPU (Graphics Processing Unit ) and CPU (Central Processing Unit ) are not good.

So the performance of that phone will be very poor and the biggest thing is that both of these should be good if we have to get better performance in the phone because you must have understood that watching GPU vs CPU, what is the importance? You must share your thoughts in the comment.
