PCI-X is an extension of the PCI bus intended for servers and high-end workstations. It has a 64-bit data bus (most conventional PCI slots are 32-bit) and operates at up to 533 MHz (PCI slots operate at 33 or 66 MHz). PCI-X slots can be distinguished by having a longer edge connector than their PCI cousins. PCI cards and PCI-X cards are interchangeable and can be used in one another’s slots, with some performance degradation.
