Theoretically, the (approximate) maximum bandwidth that a PCle x16 slot, version 5.0 can offer is _______.

PCIe is now standardized in five major versions: 1.x, 2.x, 3.0, 4.0, and 5.0. A single bidirectional lane in each of the five models operates at a data throughput of 250 MBps, 500 MBps, about 1 GBps, approximately 2 GBps, and nearly 4 GBps. Each PCIe slot can support up to 16 lanes, with the number of lanes denoted by x1, x4, x8, or x16. (The letter x is pronounced by.) As a result, a PCIe 5.0 x16 slot can handle up to 64 GBps of bandwidth. (16 x 4 = 64).
