A Graphics Processing Unit (GPU) is a single-chip processor primarily used to manage and boost the performance of video and graphics.
A graphics card (also called a display card, video card, display adapter, or graphics adapter) is an expansion card which generates a feed of output images to a display device (such as a computer monitor). Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics. At the core of both is the graphics processing unit (GPU), which is the main part that does the actual computations, but should not be confused as the video card as a whole, although “GPU” is often used to refer to video cards.
This tutorial will show you different ways to check what graphics card or GPU is in your Windows 7, Windows 8, and Windows 10 PC.
