Definition - What does Accelerated Graphics Port (AGP) mean?

An accelerated graphics port (AGP) is a point to point channel that is used for high speed video output. This port is used to connect graphic cards to a computer's motherboard. The primary purpose of an AGP is to accelerate 3D graphics output for high definition video. AGP provides much faster connectivity and throughput compared to PCI. An AGP is primarily designed to be used for 3D graphics, high definition games and engineering/architecture graphics.

Earlier, P-II computer machines (x86 supported) were designed with AGP. AGP is Intel's product and is available in many different versions. AGP offer several key features: High definition graphics throughput: the high speed video output increases the quality of the graphics displayed by the computer. Dedicated communication: an AGP can provide dedicated communication between the processor and slot. It increases clock speed and also uses RAM to copy the graphics information before loading. Moreover, AGP keeps refreshing the display screen of monitor to keep boosting the pixel powers. Compatibility and flexibility: an AGP allows all kinds of AGP cards to connect with forwards and backwards compatibilities. AGP cards can easily work with AGP-Pro slots. However, AGP-Pro cards do not work with AGP cards. All AGP cards share voltage compatibility.
