PCIe® 6.0 Specification Released to Members: Double the Bandwidth for Next-Generation Applications

We are pleased to commence 2022 on a high note with the official release of the PCI Express® (PCIe®) 6.0 specification to members. The new specification comes less than three years after the announcement of the PCIe 5.0 specification and delivers on PCI-SIG’s® promise to double the bandwidth with each specification release.  This next step in the evolution of PCIe 6.0 technology benefits data-intensive markets like High Performance Computing (HPC), Data Center, Edge, Artificial Intelligence and Machine Learning (AI/ML), Automotive, Internet of Things (IoT) and Military/Aerospace and further strengthens PCI Express as the defacto interconnect for high-speed interfaces.

The key benefits of the PCIe 6.0 specification include:

  1. Double the Bandwidth: Increases the data rate to 64 GT/s, doubling the data rate of the PCIe 5.0 specification and providing a maximum bidirectional bandwidth of up to 256 GB/s for x16 lanes
  2. Low Latency: Utilizes fixed-size Flow Control Unit (Flit)-based encoding, which allows the use of a lightweight Forward Error Correction (FEC) with Pulse Amplitude Modulation with 4 levels (PAM4) signaling and a strong cyclic redundancy check (CRC) – with no impact to latency
  3. Backwards Compatibility: Maintains compatibility with all previous PCIe technology generations, protecting customer investments and supporting connectivity to millions of existing products
