PCIe® 6.0 Specification, Version 0.5: Now Available to Members

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.

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
  • Backward 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 aligned 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.
