What is AGP (Accelerated Graphics Port)? Definition
What does AGP stands for? The acronym AGP stands for Accelerated Graphics Port.
What is AGP? Definition: AGP is a type of expansion slot designed specifically for graphics cards. It was developed by Intel Corporation in 1996 as an alternative to the PCI standard. AGP cards are slightly longer than PCI cards. AGP is based on PCI; it was designed specifically for the demands of performance 3-D graphics on personal computers.
AGP introduces a dedicated point to point channel allowing the graphics controller use the computer’s random access memory (RAM) to refresh the monitor image and to support the texture mapping, z-buffering, and alpha blending required for 3-D image display.
AGP channel is 32 bits wide and runs at 66 MHz, this translates into a total bandwidth of 266 MBps, as opposed to the PCI bandwidth of 133 Mbps. AGP also supports two optional faster modes, with yields of 533 Mbps and 1.07 Gbps.
AGP slots are built into a computer’s motherboard. They have a similar form factor to PCI slots, but can only be used for graphics cards.
There are several AGP specifications as AGP 1.0, 2.0, and 3.0, which each use a different voltage. Therefore, AGP cards must be compatible with the specification of the AGP slot they are installed in.
AGP previously replaced the use of PCI interfaces for video but AGP has been superseded by PCI Express, which was introduced in 2004. Most desktop computers manufactured after 2006 do not include an AGP slot.
