PCI-SIG® has released the PCI Express® (PCIe®) 7.0 specification, version 0.9 for member review. Version 0.9 is the final draft of the specification wherein members perform internal reviews of the technology for their essential patents. No additional functional changes are expected during this time, and the full specification is on track to be published later this year. With this update, PCI-SIG is proud to continue their frequency of doubling the data rate every three years, from 64 GT/s of PCIe 6.0 specification to 128 GT/s raw bit rate.
The PCIe 7.0 specification is targeted to support data-intensive market segments such as Hyperscale Data Centers, High-Performance Computing, and Military/Aerospace; and emerging applications like AI/ML, 800G Ethernet, and Cloud Computing. It is being developed with the following feature goals:
- Delivering 128 GT/s raw bit rate and up to 512 GB/s bi-directionally via x16 configuration
- Utilizing PAM4 signaling
- Focusing on the channel parameters and reach
- Improving power efficiency
- Continuing to deliver the low-latency and high-reliability targets
- Maintaining backwards compatibility with all previous generations of PCIe technology
