PCI Express 6.0 technology will double the data rate to 64 GT/s while maintaining backward compatibility with previous generations and delivering power efficiency and cost-effective performance. The first test products can be designed with pcie 6.0. 'Version 0.5' is not yet the final specification. The final version will be unveiled in 2021.

-- PCI-SIG -- We are starting 2020 with the release of version 0.5 of the PCI Express (PCIe) 6.0 specification incorporating the significant member feedback received on version 0.3. After momentous progress, we are proud to share that we are still on track to deliver the final PCIe 6.0 specification in 2021. If you are a PCI-SIG member interested in voicing your feedback on future specification installments, we invite you to visit the members only section on the PCI-SIG website to learn more about how your company can become involved in work groups. If you haven’t yet joined PCI-SIG but are interested in shaping the future of the interconnect of choice, please visit the Become a Member page on our website for more information.

PCIe 6.0 Specification Features Overview

• Data rate of 64 GT/s speeds, doubling the 32GT/s data rate of the PCIe 5.0 specification
• PAM-4 (Pulse Amplitude Modulation with 4 levels) encoding
• Low-latency Forward Error Correction (FEC) with additional mechanisms to improve bandwidth efficiency
• Backwards compatibility with all previous specification generations

By doubling the bandwidth and diligently maintaining our strict timeline, we believe that we will be able to deliver the industry’s needs for throughput in line with their timelines. Emerging data-hungry markets like Artificial Intelligence, Machine Learning, High-Performance Computing and more, demand additional speed and capabilities that the newest PCI-SIG architecture will easily fulfill.
