What Does A GPU Do For Gaming? Is It Important?

People throw around the term “GPU” a lot when it comes to gaming, but not many people understand what it really is. Many gamers just know that a GPU is important without necessarily knowing how it impacts gameplay. So, what does a GPU actually do for gaming?

This article explains what a GPU does for gaming and why it’s so important. I’ll also explain the effects of GPU on FPS and what to look for when choosing one. Read on to learn everything you need to know about a GPU before you buy your next gaming computer!

Do You Need A GPU For Gaming?

The GPU is perhaps the most critical piece of hardware for PC gaming. For most modern games, you definitely need a GPU in order to play them. A powerful GPU will make the gaming experience much smoother with a high frame rate.

Your computer needs to do millions of calculations to generate a 3D image. This is what’s known as pixel shading. As games have become more complex, the work of performing these calculations has moved away from the CPU and into a dedicated GPU, or graphics processing unit.

The GPU helps perform these calculations quickly, allowing the CPU to work on more complex stuff like controlling the inputs and outputs of your computer.

The reason why a CPU alone struggles with graphics is simple: microprocessors are designed to handle only one complex task at a time. Thus, a CPU is not very good at processing pixel rendering, which requires a lot of simple calculations to run simultaneously.

This is where the GPU comes in. It has thousands of cores that can handle these calculations quickly and efficiently. This allows you to enjoy seamless gameplay with high frame rates and beautiful graphics.

Does GPU Affect FPS?

A GPU affects FPS because it helps render graphics on the screen. The more powerful the GPU, the faster it’ll render graphics, resulting in a higher FPS. This means the type of GPU you have will directly impact the FPS you end up with.

FPS stands for frames per second, and is also known as the frame rate or refresh rate. The FPS will impact the user experience when gaming, as a computer with a low GPU will not be able to render an adequate FPS for a smooth gaming experience.

When choosing a GPU, you should look for one with many cores. This will allow you to run games at high resolutions and high frame rates. You should also make sure that the GPU is compatible with your motherboard and has enough memory (VRAM) to support the games you want to play.

Cooling is also important for GPUs. You should make sure that the GPU you choose has a good cooling system, otherwise it may overheat and cause lagging or even damage your computer.

Is A 4GB Graphics Card Enough For Gaming?

A 4GB graphics card can be enough for gaming if you play at a resolution of 1920×1080 or lower. However, if you want to elevate your gaming experience to the max by playing in 4K resolution or using virtual reality technology, you’ll need a graphics card with more than 4GB of VRAM.

I have used a 4GB graphics card for gaming for a while now and haven’t had many problems. I usually play games that aren’t too graphic intensive, such as League of Legends or World of Warcraft. I’ve also tried using a 6GB graphics card and I did notice a slight difference in display quality, although nothing significant enough to make a big difference.

For most titles, 4GB of VRAM will probably be sufficient. But if you want to future-proof your PC, or if you are interested in VR, then you may consider a GPU with more than just 4GB of dedicated VRAM.

Is 8GB GPU Overkill?

An 8GB GPU isn’t overkill for gaming if you want to have the best gaming experience. I would recommend an 8GB GPU to people who play at resolutions of 2560×1440 or higher. If you’re using a virtual reality headset, then you’ll definitely need an 8GB GPU or higher.

An 8GB graphics card provides enough VRAM for most games, and it also allows for future growth. I wouldn’t recommend going with a 4GB or 6GB graphics card if you plan to use a virtual reality headset in the near future. This is because this VRAM isn’t enough to run the complex calculations needed for virtual reality gameplay.

Some GPUs come with 16GB of VRAM, and I think they’ll become the gold standard for virtual reality gaming. These GPUs provide enough VRAM for any game, and they also help future-proof your gaming rig. If you are not on a tight budget, then I recommend going with the 16GB option from the start.

What To Look For In A GPU?

The most important thing to look for when shopping for a GPU is VRAM. You want to make sure you have enough RAM to support the games you want to play. Other factors to consider are the number of cores on the graphics card as well as its manufacturer, either AMD or Nvidia.

In addition to VRAM, you may want to consider the number of cores, as well as the type/speed of VRAM. Putting all of these factors to form a comparison can be quite challenging, so most people rely on benchmark scores to compare GPUs.

For example, User Benchmark is a popular website that allows users to test the power of their GPU. They catalogue the results and make rankings of the most powerful GPUs based on the average scores.

You’ll also want to consider your budget. There are many high-quality graphics cards out there that come in a wide price range. Sometimes, newer models are more expensive without necessarily being more powerful. So, going with an older model isn’t always a bad idea as they already have in-depth reviews and a proven track record.

Final Thoughts

A GPU is the graphic card that your computer needs to run images smoothly. A 4GB graphics card can be enough for some gamers, but you need more VRAM if you want a better gaming experience. More intense gaming activities such as playing in 4K or using virtual reality technology will also require at least an 8GB GPU.

So, if you’re looking to buy a new graphics card, I would recommend going with an 8GB or 16GB option. It would also help if you considered the graphics card manufacturer—AMD or Nvidia—and your budget when making your decision.
