PCI Express (PCIe)

The PCI Express (PCIe) bus is high-speed (2.5 Gb/s) serial (point-to-point) replacement of the older, shared, parallel PCI/PCI-X bus. Unlike PCI, which shares bandwidth with all devices on the bus, each PCI Express (PCIe) device receives dedicated bandwidth. The bandwidth of PCI Express (PCIe) in a x1 slot is more than double that of the PCI bus.
