The True Power behind Gaming: CPU vs GPU

Written By : Ayush Bharal



Modern digital games have gotten so much better that they have graphics which seem ultra realistic. These days ‘RPG’ and ‘triple A’ games are so much developed and feature rich that their sizes have grown exponentially. Many games reach upto 60 GB to download. These large size files require power to get rendered and to be shown on your screen. So what is the power source behind all these graphics to be shown, huh? CPU or GPU

Firstly lets talk about the work of CPU and GPU separately :

CPU


CPU or processor to be precise is the brain of the computer. As its name suggest, its main function is to process the information coming in or going out of the computer. It works as an intermediate which recieves data from source, transform it into such a form which can be transferred faster and efficiently to its destination. It is expert in calculations but it works on serial computing and can do one thing at a time. It is the component which supports and handle your Hard disk, RAM, GPU, etc. and thus it is the brain of the computer.

GPU


It is a kind of processor that has its own memory and is designed solely for the purpose of processing of graphics in Games. GPU works in conjunction with the CPU and needs the processed Data from CPU. GPU is designed for performing multiple parallel tasks at once. For Example, In a game when a player walks ahead, new trees and land starts to form in the game on screen at the same time as the player starts to move. This all happens with the help of Parallel compunting in GPU.

So what powers your game ?

Games show amazing graphics with a high frame rate. This is done only with the help both CPU and GPU. Processor provides the information and then GPU use that information and create stunning graphics with that data. GPU cannot run without the help of CPU but CPU has to do basic tasks so it can easily run without a GPU. A GPU cannot be used instead of a CPU either.
