PCI Express
PCI Express (PCIE) is the next generation bus architecture and is compatible with the current PCI software environment while offering low-cost with scalable performance for the next generation of computing and communications platforms. PCIE is a serial technology with point-to-point connection to provide 2.5 Gbit/s per lane which is 2 times faster than current PCI technology. PCIE is scalable to form multiple lanes like x1, x2, x4, x8, x16, and x32.
