The official PCI Express 7.0 specification is available today to PCI-SIG members. PCI Express 7.0 aims to open new doors for AI / machine learning, cloud, 800G Ethernet, Quantum computing, and more. PCI Express 7.0 delivers a 128GT/s raw bit rate, up to 512 GB/s bi-directionally in an x16 configuration, PAM4 signaling, improved power efficiency, and still maintains backwards compatibility with prior PCIe revisions.

PCI-SIG also announced today the PCIe Optical Interconnect Solution. The new Optical Interconnect specification is for higher PCIe technology performance and builds off the PCIe 6.4 and PCIe 7.0 specifications to have a PCIe retimer-based solution for PCIe technology over optical fiber. PCIe Optical Interconnect extends the reach of PCI Express across server racks and pads and allows for multiplexing and additional features.
