Graphic Accelerators/GPU


What is the difference between a GPU and a video card?  If I have a GPU would I need a video card?

Dear Debbie,

A graphics processing unit or GPU is a specialized processor that offloads 3D graphics rendering from the microprocessor. It is embedded in systems, mobile phones, personal computers, workstations, and game consoles.

A video card, video adapter, graphics-accelerator card, display adapter, or graphics card is an expansion card which has a GPU in it .

Its depends on user requirement to use embedded GPU in Computer Processor or buy a Separate "graphics card' Video card usually Gamers,Graphics software users etc. require that External graphics card.

So if you use computer for general applications which require min or less 3d graphics usage or video processing capabilities  then there is no need for buying or installing External graphics card.
