A physics card is an expansion card for computers, which is used to process physics interactions as to help produce more physical action in computer generated graphics. By taking over the processing of these effects, the CPU can use more of its power for other tasks. A physics card is centered around a physics processing unit, similar to the graphics processing unit on a graphics card, and also contains RAM for use in its processes. The first physics card created was the PhysX by AGEIA, released in 2006.
