A video card (also called a graphics card, display card, graphics adapter, or display 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, 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 with the video card as a whole, although "GPU" is often used as a metonymic shorthand to refer to video cards.

Most video cards are not limited to a 6 inch simple output.[further explanation needed] Their integrated graphics processor can perform additional processing, removing this task from the central processor of the computer.[1] For example, Nvidia and AMD (previously ATI) produced cards that render the graphics pipelines OpenGL and DirectX on the hardware level.[2] In the later 2010s, there has also been a tendency to use the computing capabilities of the graphics processor to solve non-graphic tasks, which can be done through the use of OpenCL and CUDA. Video cards can also be used for AI training.[3][2]

Usually, the graphics card is made in the form of a printed circuit board (expansion board) and inserted into an expansion slot, universal or specialized (AGP, PCI Express).[4] Some have been made using dedicated enclosures, which are connected to the computer via a docking station or a cable. These are known as eGPUs.
