AGP
Accelerated Graphics Port

The Intel corporation announced,the video cardand private bus (channel) standard between main memory. Because the graphic card needs mass memory capacity just in order to indicate 3 dimensional graphics, if just the necessary timeit hasallotting memory capacity from main memory,the memory (in comparison withmain memoryhigh price) whichis loaded onto the graphic card may be little. However because this data transfer to dovia the former PCI bus, the load is heavy, AGP was developed as a private channel.As forbus width being32bits, as for transfer rate 266MB/s 4 types of normal mode (AGP 1x), 2 timemode (AGP 2x) of 533MB/s, 4 time mode (AGP 4x) of 1.06GB/s and 8 time mode (AGP 8x) of 2.13GB/s are standardized.
