AGP: The AGP (Accelerated Graphics Port) port was developed by Intel in 1996 as a high performance graphic port, to solve the bottleneck that was created in the PCI graphics. Its specifications start from those of the PCI 2.1 bus, in the case of a 32bit bus.

PCI: It is a standard computer bus to connect peripheral devices directly to your motherboard. These devices can be integrated circuits fitted in it (so-called «planar devices» in the PCI specification) or expansion cards that fit into connectors.
