PCIe
Definition
PCIe (Peripheral Component Interconnect Express) is the high-speed serial bus standard used to connect hardware components in computers. Each PCIe generation doubles the per-lane bandwidth: Gen 3 (8 GT/s), Gen 4 (16 GT/s), Gen 5 (32 GT/s), Gen 6 (64 GT/s). PCIe is the interface for NVMe SSDs, GPUs, network adapters, and accelerators. A PCIe Gen 5 x16 slot delivers 64 GB/s of bidirectional bandwidth.
