This model provides an
4x slot. The AGP 4x is a bus interface targeted for high-performance 3D graphic. AGP supports only memory
read/write operation and single-master single-slave one-to-one only. AGP uses both rising and falling edge of the 66MHz clock, for 2X AGP,
the data transfer rate is 66MHz x 4bytes x 2 = 528MB/s
and
AGP 4x mode, 66MHz x 4bytes x 4 = 1056MB/s.
