PCI-SIG® has continued to host PCI Express® (PCIe®) Compliance Workshops throughout 2021 as we recognize that they are an important member benefit.

I am excited to report that PCI-SIG has released PCIe 6.0 specification, version 0.9 to our members. This is a major milestone in our continued effort to double the data rate of the PCI Express® specifications while maintaining backwards compatibility.

The upcoming PCIe® 6.0 specification introduces Flow Control Unit (FLIT) encoding, which enables the specification to provide low latency with high efficiency. FLIT mode is adopted for the PCIe 6.0 architecture because error correction needs to operate on fixed sized packets.

With the widespread adoption of compute-intensive workloads – such as artificial intelligence and machine learning – in enterprise and cloud data centers, high-speed, low-latency interconnects like PCI Express^® architecture are required to connect high-performance nodes.
