GPU stands for graphics processing unit. The Term GPU was introduced by Nvidia in 1999. It is essentially the brains of integrated graphics or a video card. A GPU processes graphics on a monitor like a CPU processes computer information. They are inside of computers, tablets, gaming consoles, and smartphones. There are stand alone GPUs that work with a separate video card and there are integrated GPUs that are found on the motherboard or next to the CPU. A stand alone GPU uses dedicated RAM while an integrated GPU uses computer memory. High quality GPUs are important for gaming.
