All computers have graphics hardware that handles everything from drawing your desktop and decoding videos to rendering demanding PC games. Most modern PCs have graphics processing units (GPUs) made by Intel, NVIDIA, or AMD.
While your computer’s CPU and RAM are also important, the GPU is usually the most critical component when it comes to playing PC games. If you don’t have a powerful enough GPU, you can’t play newer PC games—or you may have to play them with lower graphical settings. Some computers have low-power “onboard” or “integrated” graphics, while others have powerful “dedicated” or “discrete” graphics cards (sometimes called video cards.) Here’s how to see what graphics hardware is in your Windows PC.
On Windows 10, you can check your GPU information and usage details right from the Task Manager. Right-click the taskbar and select “Task Manager” or press Windows+Esc to open it.
Click the “Performance” tab at the top of the window—if you don’t see the tabs, click “More Info.” Select “GPU 0” in the sidebar. The GPU’s manufacturer and model name are displayed at the top right corner of the window.
You’ll also see other information, such as the amount of dedicated memory on your GPU, in this window. Windows 10’s Task Manager displays your GPU usage here, and you can also view GPU usage by application.
If your system has multiple GPUs, you’ll also see “GPU 1” and so on here. Each represents a different physical GPU.
On older versions of Windows, such as Windows 7, you can find this information in the DirectX Diagnostic Tool. To open it, press Windows+R, type “dxdiag” into the Run dialog that appears, and press Enter.
