[[PCIe]] 3.0 at 8 lanes doesn't have sufficient throughput to carry a full 100Gbps; its theoretical max is 7.877GB/s or 63.016Gb/s. PCIe 4.0 at 8 lanes or PCIe 3.0 at 16 lanes are necessary. A full 200Gbps signal (or two 100Gbps ports) requires 16 lanes of PCIe 4.0 or 8 lanes of PCIe 5.0. A full 400Gbps signal (or two 200Gbps ports) requires 16 lanes of PCIe 5.0, 8 lanes of PCIe 6.0, or 4 lanes of PCIe 7.0. | [[PCIe]] 3.0 at 8 lanes doesn't have sufficient throughput to carry a full 100Gbps; its theoretical max is 7.877GB/s or 63.016Gb/s.
