AGP definition by American Heritage Dictionary
agp - Computer Definition
(Accelerated Graphics Port) A hardware interface from Intel for connecting a display adapter (graphics card) to a PC. Superseded by PCI Express, a single AGP slot on the motherboard provided a direct connection between the card and memory. AGP was introduced as a higher-speed alternative to PCI, and it freed up a PCI slot for another peripheral device. The original AGP standard (AGP 1x) provided a data transfer rate of 264 MB/sec. AGP 2x, 4x and 8x increased the rate to 528 MB/sec, 1 GB/sec and 2 GB/sec. See AIMM, PCI Express, PC data buses and motherboard.
