PCIPCIe
PCIPCIe is not a recognized standard in itself; the term is most likely a typographical conflation of PCI and PCIe (PCI Express). PCI Express is a high-speed serial computer expansion bus standard designed to replace older PCI and PCI-X interfaces. It uses a point-to-point topology with lanes that can be combined to form configurations such as x1, x4, x8, or x16. Each device connects to the motherboard over a dedicated link that negotiates speed and width at power-up. The PCI-SIG organization develops and maintains the PCIe specifications, with multiple generations offering increasing bandwidth and improved efficiency.
Generations of PCIe range from 1.x through 6.x. Each new generation increases per-lane throughput and often
Common uses of PCIe include graphics processing units, solid-state drives (notably NVMe-based drives), network adapters, and
Compatibility and evolution are governed by design goals of backward and forward compatibility within limits: older
