The MK77M / MK77M II provides an
2x4x slot. The AGP 2x4x 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. AGP is now moving
to AGP 4x mode, 66MHz x 4bytes x 4 = 1056MB/s.
