A graphics accelerator card is a PCI, AGP, or PCI-E expansion card that improves graphics calculation and video performance. It incorporates its own GPU and memory, and may contain hundreds or thousands of GPU cores. If the GPU contains specialized hardware for accelerating 3-D graphics, it may also be called a 3-D accelerator.
