AGP : Computer Hardware Buyers’ Glossary
AGP (Accelerated Graphics Port). A high performance way for video cards to access the
CPU (Central Processing Unit). They bypass the PCI (Peripheral Component Interconnect)
bus that other devices use and go direct to the CPU,
much the way RAM (Random Access Memory) does. To use it, you must have an
motherboard with a special AGP slot and an AGP
video card. You cannot use the older PCI
video cards in AGP slots or vice versa.
