Is a GPU a Graphics card?

Looking at the specifications of a laptop or computer can be extremely confusing. Between the GPU’s, the graphics cards, the RAM’s and the SSD’s, it’s easy to see why many people get confused with everything.

One of the most commonly asked questions is whether a GPU and a graphics card are the same thing, or are they actually different from one another. Whilst it’s a great question, it’s actually very easy to explain the difference between the two.

Is a GPU a Graphics card?

If you’re trying to work out the difference between the two, then don’t worry. Here’s a simple explanation of the difference between a GPU and a graphics card.

The correct answer is that a GPU is technically part of the graphics card, and it’s not the graphics card itself. So whilst they aren’t exactly the same thing, they are related and most people refer to them as being the same thing, or use the terms interchangeably with each other.

What is a GPU?

The term GPU was actually created by Nvidia, who are one of the biggest producers of graphics cards.

GPU stands for Graphics Processing Unit. The GPU is the most important part of any graphics card, and it’s responsible for processing and rendering graphics. In some ways, it’s actually similar to the processor in relation to the motherboard. However, the GPU’s job is to mathematically process graphics, which is a complicated job.

These GPU’s use various different complex methods to make the images and objects appear easier on the eye. One example of this is anisotropic filtering, which enables the processor to give textures to the images that are shown on your screen. To do this, we need to use more processor power, which is one of the reasons why these products can be expensive.

There are actually two different types of GPU. You can get integrated GPU‘s, which is actually built in with the computer or laptops processor (CPU). They actually share memory with the processor, so many people prefer to get a discrete GPU. This type of GPU is separate, so you don’t end up using memory from another part. In most new devices, discrete GPU’s are used.

What is a graphics card?

So, we know that the. GPU is part of the graphics card. But what does a graphics card even do?

Well, a graphics card is responsible for translating the data from your computers processor and essentially turning it into a picture. It does this by changing what’s displayed on the pixels in the monitor – this can be more than a million different pixels for higher resolution displays. When a graphics card is creating an image on your display, it generally outlines it first, then it fills in the different pixels based on the data that it is fed (this is what rasterizing is).

We can break this down into four different parts to understand how the graphics card works.

  • The card needs to be connected to the motherboard of your computer. This is where it collects all the data from, as well as power giving it the ability to work.
  • The processor deciphers data and tells us what we want to show in each pixel on the display.
  • We need some form of memory, which holds the data of what we’re going to fill each pixel with.
  • Finally, obviously we need to be connected to some sort if display/monitor so we can see what data we are getting.

This is quite simply what a graphics card is used for, and how it works with the rest of your laptop/computer.

What are the most popular GPU brands?

If you’ve been buying laptops or computers for a while, then you’ll probably heard of the two brands Nvidia and AMD. Both companies are headquartered in California, and although Nvidia is the bigger company, they are both billion dollar businesses.

Comparing the two brands to each other is one of the most commonly argued things between tech nerds on the internet, and they’ll probably all give you a different opinion. However for the most part, people still tend to side with Nvidia as they are the bigger brand of the two and they generally make more powerful graphics cards.

Conclusion

In conclusion, it’s clear to see the difference between the two terms, as a GPU is actually part of a graphics card. However, when most people are speaking about GPU’s, they may refer to it as a graphics card, because the GPU is actually the integral part of the graphics card.
