The Accelerated Graphics Port is a high-speed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics. Originally it was designed as a successor to PCI type connections. Since 2004, AGP has been progressively phased out in favor of PCI Express. By mid-2008, PCIe cards dominated the market and only a few AGP models were available.
