PCI Express (PCIe) has become the leading interconnect technology to succeed the Peripheral Connect Interface (PCI) architecture. The PCI Express(PCIe) architecture retains the PCI usage model and software interfaces for investment protection and smooth development migration. The technology is aimed at multiple market segments in the computing and communication industries, and supports chip-to-chip, board-to-board and adapter solutions. PCI Express 5.0 currently runs at 16GT/s or 32Gbps per lane in each direction, providing a total bandwidth of 128GBps in a 16-lane configuration which is the largest size in use.
