In a computer system, GPU (Graphics Processing Unit) plays a role to handle anything related to graphics processing. From video rendering when you are editing video, decoding videos, drawing, image editing, and so on. GPU is the first component you should see when you are planning to buy a new computer for graphic design, image editing, video editing, and gaming.
How to know the graphics card on a computer?
On Windows 10, there are at least two ways to check the graphics card on your computer. First, you can do so via Task Manager. Open Task Manager (Ctrl+Shift+Esc) and click the Performance tab. If you don’t see this tab, click More details on the bottom side of the Task Manager window. Select GPU 0 the left sidebar to see the information about the graphics card on your computer. There are several pieces of information you can find here, like the amount of dedicated GPU memory, shared GPU memory, physical location, and so on.
If there are more than one graphics cards installed on your computer, you will see GPU 1 on the left sidebar under the Performance tab on the Task Manager window.
Alternatively, you can also check the GPU information via DirectX Diagnostic Tool. To open it, open the Run dialog (Windows+R) and type
dxdiag and hit enter. Once the DirectX Diagnostic Tool window opens, click the Display tab.
As you can see, there are also information related to your graphics card such as chip type, manufacturer, total memory, shared memory, and so on.
