The PCI-SIG first unveiled the Pcie Express (PCIe) 7.0 specification at US DevCon in June 2022 with claims of bidirectional data rates of up to 512GB/s in x16 configuration, and the standard is now getting closer to the full release in 2025 with the release of the specification version 0.5. PCIe 7.0 increases data transfer speeds to 128 GT/s per pin doubling the 64 GT/s of PCIe 6.0 and quadrupling the 32 GT/s of PCIe 5.0, delivering up to 256 GB/s in each direction in x16 configuration, excluding encoding overhead. In other words, the total maximum bandwidth of a PCIe 7.0 x1 interface (32GB/s) would be equivalent to PCIe Gen3 x16 or PCIe Gen4 x8 as shown in the table below. PCIe 7.0 highlights: 128 GT/s raw bit rate and up to 512 GB/s bidirectionally via x16 configuration PAM4 (Pulse Amplitude Modulation with 4 levels) signaling Doubles the bus frequency [...]
