Bus Speed for PCIe-6537/6536

Hardware: Digital I/O (DIO)>>High-Speed>>PCIe-6537

Problem: What is the bus speed for my PCIe-6536/6537?

Solution: The PCIe-6536/6537 has a bus speed of 250MB/s, which is a 1x architecture.  Below are some of the bandwidths for different types of architectures :


MAX Bandwidth
Bus
Bandwidth
PCI 132 MB/s
AGP 8X 2,100 MB/s
PCI Express 1x 250 [500]* MB/s
PCI Express 2x 500 [1000]* MB/s
PCI Express 4x 1000 [2000]* MB/s
PCI Express 8x 2000 [4000]* MB/s
PCI Express 16x 4000 [8000]* MB/s
PCI Express 32x 8000 [16000]* MB/s
IDE (ATA100) 100 MB/s
IDE (ATA133) 133 MB/s
SATA 150 MB/s
Gigabit Ethernet 125 MB/s
IEEE1394B [Firewire] 100 MB/s

NOTE : Since PCI Express is a serial based technology, data can be sent over the bus in two directions at once. Normal PCI is Parallel, and as such all data goes in one direction around the loop. Each 1x lane in PCI Express can transmit in both directions at once. In the table the first number is the bandwidth in one direction and the second number is the combined bandwidth in both directions. Also, please note that in PCI Express bandwidth is not shared the same way as in PCI, so there is less congestion on the bus.
