Graphics Processing Unit (GPU)

The GPU was built for a different problem.
Everything on your screen is made of tiny dots called pixels.
To draw a picture, the computer has to decide what color millions of pixels should be. Many tiny decisions, all at once.

So the GPU took a different approach. Not one powerful processor, but thousands of simpler ones, all running at the same time.

Did you know?

To show video or games, a computer draws one still image after another, fast enough that the pictures become motion. The number of images shown each second is called FPS: frames per second. Movies often use 24fps. Games often aim for 60fps or more because smoother motion makes controls feel more immediate.
