What Matters Most for PC Gaming: GPU or CPU?(Explained)

What Matters Most for PC Gaming: GPU or CPU? Some PC choices for gaming are simple. For instance, you should upgrade the storage space on your solid-state drive or hard disk drive, depending on the question you are asking.

But some choices are considerably trickier to make than others. It is harder to determine whether you should improve your GPU or CPU. We are available to assist with that choice.

The Overview of CPU and GPU

What does a CPU do?

The central processing unit (CPU), often known as the “processor,” executes and manages the instructions given by a computer program by carrying out input/output (I/O) operations, simple arithmetic, and logic.

The CPU is a crucial component of every computer and is responsible for receiving, directing, and processing data.

It’s frequently referred to as the “brain” or “heart” of the desktop or laptop PC because it’s typically the most crucial component, depending on which body part you’d consider the most significant. And it’s a crucial part of the gaming system when it comes to gaming.

The term “core” for a CPU is also a synonym for the processor found in a CPU. In the past, processors only had one core that was dedicated to a single task.

However, modern CPUs feature 2 to 28 cores, each of which is dedicated to a different function. So a single chip with two or more CPU cores is a multi-core processor.

What does a GPU do?

The generation and rendering of images, videos, and animations are sped up by the graphics processing unit (GPU), commonly known as the graphics card or video card.

It allows the CPU to focus on other activities while quickly performing math operations.

There are two different types of GPUs: the first is an integrated (or embedded) GPU that is physically attached to the CPU and shares memory with it. The other, however, is a separate GPU with its memory and card.

When it comes to playing certain kinds of games, the GPU is frequently even more vital than the CPU as a part of a gaming system.

A GPU is a single-chip processor that is primarily used to control and improve the performance of video and graphics.

What distinguishes the “core” functions of the CPU and GPU?

A GPU is designed for multitasking; it has hundreds to thousands of tiny cores to manage thousands of threads (or instructions) simultaneously.

A CPU uses many cores that are focused on sequential processing.

Through the use of Hyper-Threading technology, some CPUs can act as if they have two independent virtual (or “logical”) cores or threads within a single physical core.

The aim is to divide the workload among them and increase the number of concurrently running instructions acting on different sets of data to improve performance.

CPU or GPU: Which is more crucial for PC gaming?

The GPU is frequently praised as being the most crucial component for PC gaming. That’s because the images, scenes, and animations you see are rendered by the GPU.

The majority of today’s fast-paced games are very taxing on the GPU’s rendering capacity. These games are also made to benefit from the additional cores and threads that newer CPUs provide.

The CPU and GPU are both signed on their own. An intelligent CPU and a potent GPU are needed for demanding games.

However, it depends on what they will be used for primary and which games, in particular, will be utilized to determine how important they are for PC gaming.

During a game, CPUs are used for activities that the GPU isn’t particularly good at, such as the artificial intelligence (AI) of non-player characters (NPC). However, the GPU performs a lot of things better.

Some games benefit from having more cores because they utilize them better. Others might not, as they are designed to just use one core, and a faster CPU makes the game run more smoothly.

It won’t have enough power to run otherwise, and it will be sluggish.

For instance, Minecraft just uses one core, thus it doesn’t require additional power. In this instance, the only factor affecting frames per second (FPS) during the game is the speed of the CPU.

Should I upgrade my GPU or CPU?

In an ideal situation, you would just purchase the finest of both. Sadly, financial limitations might force us to choose between the two, at least temporarily.

Nowadays, many games automatically utilize multiple cores (the quad-core CPU seems to be the most common), which results in quicker and better FPS rates. In light of this, if the cost of the quad-core processors is not too high, you should probably choose them.

Unless your GPU is an older, less powerful model, current dual-core processors can limit your graphics card and reduce the performance of your gaming session.

Additionally more inexpensive, more effective, and less sluggish than older models are quad-core CPUs. Having extra cores in your system makes sense because newer games increasingly rely on many cores rather than just CPU speed.

Choosing the premium options for either the CPU or GPU may make even more sense if you’re a dedicated gamer looking toward the future and want to make sure you can run the most resource-intensive triple-A (AAA) games to come. T

his is especially true if you can afford the astronomically high prices.

The Intel Core i9 series is one of the most potent Intel processors available right now in terms of CPU power.

With 8 cores and 16 threads, two models—the i9-8950HK and i9-9900K—offer incredibly rapid processing performance for gameplay.

Additionally, if you currently own or are intending to purchase a 4K/UHD monitor with more than 8 million pixels, you might want to think about upgrading your GPU to a card like the NVIDIA GeForce RTX 2080 Ti. But this costs more than $1,000.


If your budget is tighter, it could be a good idea to preserve some of it for your CPU as GPUs can be the most expensive component of your gaming setup.

Your gaming may suffer with reduced frame rates per second if you overspend on the GPU without paying attention to the CPU.

First, upgrade your CPU.

It makes sense to improve your CPU first if you enjoy fast-paced games like first-person shooters like Call of Duty: Black Ops 4, real-time strategy games like The Age of Empires, or MMORPGs like World of Warcraft.

First, upgrade your GPU.

On the other hand, if you primarily play online open-world games like Grand Theft Auto V or role-playing games like The Elder Scrolls V: Skyrim or The Witcher III: Wild Hunt with clearly defined, immersive environments and stunning visuals, you should first upgrade the GPU and begin saving for a new CPU.
