A graphics processing unit (GPU) is the processor on a graphics card. It makes images, animations, graphics and then displays them on the computer’s screen. A strong GPU is able to process complex animations and graphics smoothly and efficiently. Images which GPUs make may be 2D or 3D. For most applications, the GPU has to make two dimensional (2D) pictures. Some applications use 3D pictures to simulate three-dimensionality.[1][2]
