Form factors - Single-slot, full-height, full-length (FHFL)
4. Peripheral Component Interconnect Express (PCI Express, PCIe or PCI-e)
The PCI Express bus is a backwards compatible, high performance, general purpose I/O interconnect bus, and was designed for a range of computing platforms.
The PCI Express bus connects each device directly to the CPU and other system devices through a pair of high speed unidirectional differential links (transmit and recieve, respectively).
PCIe x4 features four PCIe lanes.
PCIe x1: 1 lane, 18 pins, and 25 mm in length
PCIe x4: 4 lanes, 32 pins, and 39 mm in length
PCIe x8: 8 lanes, 49 pins, and 56 mm in length
PCIe x16: 16 lanes, 82 pins, and 89 mm in length
