AX45F-1394 provides an
AGP
66-MHz clock frequency and the bandwidth are 2.1Gbytes/s. It is a great improvement on the performance of 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. Now the
transfer rate is 66MHz x 4bytes x 8 = 2112MB/s.
