The
Accelerated Graphics Port (often shortened to
AGP) is a high-speed point-to-point channel for attaching a
video card to a
computer system, primarily to assist in the acceleration of
3D computer graphics. It was originally designed as a successor to
PCI-type connections for video cards. Since 2004, AGP has been progressively phased out in favor of
PCI Express (PCIe); by mid-2008, PCI Express cards dominated the market and only a few AGP models were available.
