(agp, accelerated-graphics-port) A dedicated graphics bus slot on PC motherboards. AGP operates at 66 MHz and transfers data at a rate up to 528 MB/sec, compared to the PCI slot which runs at 33 MHz and has a maximum transfer rate of 132 MB/sec.

A key to AGP's future success is the its ability to use system memory to store and retrieve larger, more realistic textures. By using system memory rather than video memory, without incurring a dramatic performance hit, 3D application developers can utilize the greater bandwidth for more graphically intense games.

The Graphics industry is rapidly moving from PCI to AGP.
