First review draft of PCIe 7.0 specification
Version 0.3 of the next generation of PCI Express technology is now available for members of the special interest group.
“Version 0.3 of the specification indicates that the first review draft of the specification is complete and has received work group approval,” said Al Yanes, PCI-SIG President and Chair. “This is an important milestone for PCI-SIG, demonstrating we are on plan for a full specification release in 2025.
- PCI-SIG looks to PCI Express 7
- High-speed I/O connectors meet PCIe 6.0 spec
- Fast PCIe 5.0 and 6.0 cable and connector compliance
PCIe 7.0 is aimed at emerging applications such as 800 G Ethernet, AI/ML, Cloud and Quantum Computing as well as data-intensive markets like hyperscale data centres, High Performance Computing (HPC), edge and military and aerospace designs.
The aim is to support 128 GT/s data rates and up to 512 GB/s in each direction via a x16 lane configuration using PAM4 signalling. The PCIe 7.0 specification defines the channel parameters with improved power efficiency and the low latency and high reliability. It also has to maintain backwards compatibility with all previous generations of PCIe technology
“Our robust and proven specification development process, spanning three decades, continues to guide us towards success. Thanks to the hard work and dedication of our work groups, PCI-SIG is ahead of the curve in providing the industry with a high-bandwidth, low-latency interconnect for emerging markets,” said Yanes.
Members can access the PCIe 7.0 specification, version 0.3 on the members workspace.
