How Does CPU Affect Gaming

by Perfect Tech Reviewers

Gaming has become more than an act of entertainment; it is a culture, a lifestyle, or a way to see a completely different virtual perspective of the world. As technology and machine learning are evolving, we have computationally intensive games which require a CPU with top-notch features. No doubt, the CPU model, generation, speed, and cores affect game processing. But the question rises to what extent and how does it happen?

Such technological questions contain so much in themselves, one may solve riddles over riddles to know the deep-down CPU processing abilities and gaming functionality. But I will not waste your time on purposeless explanations, I will try to discuss all possible aspects in short duration so you do not find it irrelevant. After reading this guide on CPU functionality, you will be able to solve almost all riddles. Come along with me.

How Does CPU Affect Gaming?

I will cover as many aspects as I can and go into detail step by step. So, let me explain to you about the chip and CPU. Basically, the CPU is the one which controls all the instructions, in more appropriate words, it is responsible for executing all the instructions and processing calculations. The CPU also deals with the applications and provides a suitable speed to run specific applications.

So, the first job of a CPU is to execute the instructions then comes the second major function, managing system resources. The chip seems small but it has more functions than you imagine. In managing system resources, the CPU looks after all the components that each one is doing their work. Another major responsibility of the CPU is to control the operations. Such as when you turn on the system, the CPU starts working and initializes the boot procedures.

These are the major functions of a CPU but there are also multiple tasks this small chip executes. In applications, whether it is a game or editing software, the CPU starts all the functions. I have made a cycle in which steps are mentioned one by one in the context of gaming so you understand how CPU affects gaming.

CPU & Gaming

CPUs come with different specifications and speeds. Mostly, we consider these specifications as cores and generations. The more cores a CPU possesses, the more efficiently it works. For example, Core i9 is far better than Core i3. The same goes with generations, the 1st generation core i9 is less capable as compared to the 5th generation core i9. These are the two major factors that affect gaming.

CPU Cores And Their Effect On Gaming

Cores play a significant role in the speed, multitasking, and processing of data. On the other hand, a game is an amalgamation of a set of instructions managed complicatedly. Here comes the interesting fact that the CPU is responsible for reading and launching those sets of instructions. But this procedure has steps and if the CPU has fewer cores, it may take more time to launch the game.

For instance, you have an Intel core i5 CPU and you want to play a heavy game. Although the Core i5 is a good processor, if you compare it with the Core i9, definitely, the latter will win. It will launch games faster than the Core i5. Then comes the streaming and recording of the games while you play. CPU cores also matter for such purposes and if you have more cores CPU, the game will run smoothly.

CPU Generations And Their Effect On Gaming

People who are familiar with computer technology consider generations as crucial role players. Basically, generation is the series of architecture, technology, and making procedures that CPUs share. Every next-generation CPU is better, faster, and more efficient in data processing such as 2nd generation CPUs and 7th generation CPUs are completely different in speed, power consumption, and abilities.

The higher generation a CPU is, the faster clock speed it will offer. If you do not know, clock speed refers to the ability to perform calculations. I will tell you a few examples of heavy games and the clock speed they require so you understand how important it is for FPS. First is GTA 5, it is one of the best and most played games right now. The game is available in many versions. Anyhow, it requires a 3.2 GHz clock speed to go smoothly.

Then I will pick up one of the heaviest games ever developed in the history of technology, cyberpunk 2077. It is a high-end game that is known for top-quality graphics and matchless features. This game requires at least a 3.3 GHz clock speed to run smoothly. I will take another game for a better understanding, Call of Duty: Warzone. This is also the most common among gamers and is regarded as the top-heavy game. It requires a 3.5 GHz clock speed to run.

What If My CPU Is Not Much Capable?

It mostly happens when you have a less clock speed or lower core CPU. So, people ask if they can run those games, if yes, then why do they need higher cores and more generation CPUs? Actually, it does not go like this, the lower core and less generation CPUs can lift those games but they will be unable to satisfy the speed and launching needs. It is like you are lifting more weight than your capability so will you up the weight or be unable to do this?

Certainly, you will face tough times, the same goes with the CPUs. When you force them to run heavier games than their ability to stand, they will lower the speed, cause errors and sometimes stop working. What I mean to say, the CPU’s ability to process data has a significant relation with launching and running games. Here is a cycle mentioned for you to understand how a CPU works in gaming.

  1. The first step is when you click on the icon and the game launches. The CPU is responsible for executing this action of launching the game.
  2. The operating system sends your “click”, which means the action request, to the CPU to initiate the application or game.
  3. Then the CPU allocates memory by initializing the game code.
  4. Further, it starts loading files you once installed when you downloaded the game.

All these processes occur in milliseconds, yet, the CPU was preparing a playground to launch the game. Then comes the further steps such as connecting with other parts of the motherboard to perform an operation.

  1. Now you see a dark screen for just a second. It happens because the CPU connects with other parts of the motherboard to retrieve information and provide information.
  2. Then the CPU displays the game initials on the screen with the help of RAM, drives, and GPU.
  3. The CPU sends signals to the audio card to play the audio.
  4. A complete picture with audio opens in front of you on the screen.

These are the steps that occur countless times whenever you launch a game or click on any application. However, a high-speed CPU with ultimate architecture and incredible technology can tackle games efficiently. It is the CPU that deals with all functions from connecting to GPU and retrieving information from drives to initiating calculations and executing operation.


The CPU is considered the brain, like a human nervous system, it has similar functions from ordering other parts to performing their job to looking after all organs. CPU deals with applications whether it is a game or software to convert PDF files, from the beginning to the end, until you close the application. It has a major role in executing operations and if one has fewer cores and a lower generation with unmatched clock speed, it will be unable to lift the game.

Frequently Asked Questions

Does the CPU help with gaming?

CPU is a highly prominent component for running games. It deals with the major functions from retrieving the basic information from drives to tackling and loading files.

Does the CPU affect gaming speed?

Yes, the CPU affects the gaming speed. I have mentioned how high-generation CPUs deal with games and if one has a low GHz CPU, the game’s performance will be lower.
