How Does a GPU/Graphics Card Improve Your Computer’s Performance?

What is a Graphics Card?

The graphics card or (GPU) is used to show what is on your computer screen. Anything from your character’s movement in a game, to the background of your pc. The graphics card shines the light on your gaming experience. Similar to the CPU, your GPU processes information using multiple cores. However, unlike the CPU, the GPU has thousands of cores that focus solely on solving simple geometry problems. This is how your computer creates the shapes and colors that appear on your screen.

Why Can’t You Just Use Your CPU?

The short answer is yes you can use your CPU for gaming. However, it may be hard for your computer to run many games unless you have your settings turned down quite a bit. Even then, the game won’t be very smooth. Compared to a GPU the CPU has less cores, but the cores in a CPU are more complicated, and smarter then those in a GPU. The reason why this is not very efficient when rendering graphics is because a core can only focus on one task at a time.

Therefore, a GPU with thousands of less complicated cores can solve thousands of problems in less then a second. While a CPU can only solve around 8 of those problems in the same time frame. Think of this like having a 5 experienced car mechanics having to fix 100 cars. Now compare that too 100 amateur car mechanics having to fix the same 100 cars. The experienced car mechanics are better individually. However, the 100 amateur car mechanics have enough knowledge to finish fixing the cars faster then the experienced workers.

What Makes a Good Graphic’s Card

There are many things to keep in mind when picking out a good graphics card. Some things you should consider are, the clock speed, memory, memory speed, memory bandwidth, and RAMDAC speed. The two most important things to keep in mind when buying a graphics card are the GPU clock speed, and how much memory your GPU has. These two parts of the GPU will have the most impact on all the games and applications you use. This will also, most likely determine if your computer runs smoothly or not.

What is GPU Clock Speed?

Your graphics cards clock speed shows the speed of how fast your GPU can render graphics. Thus, making it very important for your graphics card to have high clock speeds in order to play games, render videos, and images at very high speeds. That is why choosing a GPU with a high clock speed is one of the most important parts to keep in mind when picking out a graphics card.

What Does the GPU Memory do?

Similar to your computers RAM, your GPU memory or (VRAM) is your graphics cards temporary storage. This makes it easier and faster for your GPU to grab memory from itself instead of from your own system. It also makes your computer work less because the GPU’s memory is separate from your systems memory. You should also keep in mind that buying a graphics card with a lot more memory than you will need will not increase performance. Just like your RAM having more memory than you need will do nothing but sit there and do nothing. Therefore, you could be wasting your money if your deciding between a GPU with 4GB of VRAM and one with 8GB.

I first got into building my own computer when I was around 12 or 13. The first computer I had ever built didn't work. So I kept researching to figure what I did wrong. I really enjoyed researching, learning, and building computers, so I decided to turn it into an online business, and here I am.
