The PCI-SIG continues to make progress on the development of the next generation of PCIe technology – the PCIe 6.0 specification.

First announced three months ago during our U.S. Developers Conference in June, the PCI-SIG members have fast-tracked development and Revision 0.3 of the specification is now complete and available to PCI-SIG member companies for review and input. PCI-SIG expects that we will be able to complete the final specification by 2021.

PCIe 6.0 technology will double the data rate to 64 GT/s while maintaining backward compatibility with all previous spec generations. Two of the key changes that are implementing include PAM-4 (Pulse Amplitude Modulation with 4 levels) encoding and low-latency Forward Error Correction (FEC) with additional mechanisms to improve bandwidth efficiency.
