accelerated graphics port

views updated

accelerated graphics port (AGP) A port specification that facilitates the high-speed high-resolution display of graphics. Developed by Intel, it provides a direct connection for data transfer between an AGP-compatible display adapter and the system's main memory. As a result, images are displayed more quickly and smoothly than is otherwise possible over a system's PCI bus. The standard 8@MAGP can support data transfer speeds up to 2.1 Gbps (as opposed to the earliest AGP standard of 264 Mbps).
