How GPU Works In Smartphone - BEGINNER

Hi Visitor,

Q. Can you imagine what is the hardware used for processing graphics as dialing a contact, watch videos, icon representation, windows sliding animation etc...?

Ans:  Smartphone GPU is a part of the SoC(Systems On a Chip) of your Smartphone CPU Chipset.

GPU is a Graphics Processing Unit used in your computer, smartphones, smart watches etc for processing the graphics on the screen. Everything you can see on screen is controlled by the GPU of that devices.

How GPU Works In Smartphone

All the content shown on your smartphone screen is processed by the GPU of the smartphone, CPU just control the programming process at the backend.All that graphical things are controlled by the GPU, Without GPU Your smartphone never looks smart, May it has lots of feature in it.

Good GPU is Needed if you want to do video editing, image processing, gaming for smooth graphics rendering.

There are mainly two types of GPUs are there, Given below:

• Internal Or Inbuilt; 
• External of Dedicated.

1.Inbuilt GPU, is the processor provided by the CPU company inbuilt, to processes regular graphics on system like them, icon images, little bit games(small quality) etc.(e.g. Smartphone GPU)

2.Dedicated GPU's, are the processor installed as per the requirement of PC.Its propose is only to process the graphical activity of the devices by taking that burden from CPU for processing.

What Is GPUs?

It is a processor almost like CPU, but this will only process the graphics. Yes.GPU also has the Number of Cores as CPU for processing the graphics.Today I will talk only about smartphone's GPU components.

GPU smartphone is provided by the Following brand; Check Which GPU your smartphone has, You will definitely get one of the following brand GPU on your smartphone:

                  - Power VR                    - Mali                      - Adreno                  - NVIDIA

Power VR: It is GPU provider company which license their GPU design to the manufacturers of the chipset.Normally Apple, Samsung, etc.This provides good quality of graphics experience to the user.That's, why it is used in smartphones, flagship phone mostly.

Mali: It is a brand which is a part of ARM Company that provide CPU architecture also to the smartphones manufacturers also.This is all very popular in GPU category.

Adreno: Adreno is a part of Qualcomm Snapdragon. You can never get this brand GPU if you don't have Snapdragon processor on your smartphone.Qualcomm never shares its GPU architecture to any other brand.

nVIDIA: It is a company which has introduced 1st Dedicated Graphics Card.This brand GPU's are also good for use as performance and quality perspective.

GPU will lessen the workload of the CPU to handle the graphics.GPU provides extra cores to games for its processing smoothly.

The performance of GPU is normally dependent on Cores, Memory, and Frequency to process graphics.

Detailed Graphics Cards With Specification Will Be There In Upcoming Article :-)

Key Components of GPU:

• Core in Graphics Processor Unit
• Frequency of GPU 
• Memory of Graphics Processor.

Core In GPU: In simple and short, suppose 1-2 cores handling all the human bodies in the game,3-4-5 handling cars/vehicles in the games,6-7-8 handle background, trees and 9-10-11-12 control the camera view while rotating angles.

In that ways, as much Cores, a GPU Has The more smooth performance you will get.Core will handle all the section and process itself without the help of CPU.

Frequency: This is a term used for the speed of switching the graphics to process.with the more frequency of GPU the cores can exchange values to each other more fastly.You can understand its importance by assuming the situation when you see your game graphics are moving very slow.So there the frequency need occur.

Memory: A GPU use its own memory; and always tries to run games on its own capabilities, without the help of CPU.So We can say that GPU has its own Memory to handle the heavy size of games; Instead, a Game grabs space from your CPU harddisk and gives a load to CPU while running.So rather than doing that, the GPU will always try to run the games by taking the size bulk on itself for its game processing.

One Important thing:

You can not say that if You buy suppose octa-core 2.5GHz smartphone, that it will provide you good graphics quality also, No that's not correct ways to think.

It is possible that maybe mid-range smartphone perform very nicely as compared to any of your high-end phones in term on graphics while playing games,captuing video, etc.

The performance of games on your smartphone totally depends on the capabilities of your GPU, not on the capabilities of CPU specification.

Example: CPU Comaprision:

Snapdragon 430 CPU                                         V s       Snapdragon 615 CPU

GPU: ARM Cortex A53,Octa Core 1.4GHz                  CPU: ARM Cortex A53,Octa Core 1.7GHz

GPU: Adreno 505GPU                                                   GPU: Adreno 405 GPU

Fail in comparison of CPU, But Pass                             Passed in normal CPU based processing But 

in Performing Gaming on smartphones                       fail in gaming performance.
