PCIe (Peripheral Component Interconnect Express) is a high-speed interface standard that connects peripherals, such as graphics cards, storage devices, and network cards, to a computer's motherboard. The PCIe specification defines the architecture, protocols, and interfaces for these high-speed connections.
: A key feature of the spec is that newer generations remain compatible with older hardware; for example, a PCIe 5.0 device can function in a PCIe 4.0 slot at 4.0 speeds. ctf.re +5 Performance by Generation 10 sites PCI Express - Wikipedia The PCI Express link between two devices can vary in size from one to 16 lanes.
