The PCI bus has been used for many years and is still running strong. This interface is being development in Servers, Datacom, and Telecom Systems. With many different PCI devices and peripheral being placed in systems today, the need for PCI Bridges becomes essential. The evolutionary PCI-X Architecture enhances system performance with better efficiency. It provides up to eight times better performance than the PCI bus. The PCI-X bus pushes the speed to 133 MHz and adds the split transaction, which makes the utilization of the bus much more efficient.
