Written by Michael Larabel in Standards on 18 September 2025 at 08:27 PM EDT. 25 Comments
As announced last month, PCI Express 8.0 is aiming for 256 GT/s speeds for allowing 1 TB/s bandwidth in an x16 configuration. In working towards the goals of PCIe 8.0, the PCI-SIG announced today that the v0.3 specification has been released to members.

PCI Express 8.0 v0.3 received workgroup approval and is now available to PCI-SIG members. The v0.3 milestone is for the first review draft of the specification and aligns with their schedule for releasing the completed PCI Express 8.0 specification by 2028.

Per the PCI-SIG announcement, the key highlights of PCIe 8.0 include:
- Delivering 256.0 GT/s raw bit rate and up to 1.0 TB/s bi-directionally via x16 configuration
- Reviewing new connector technology
- Confirming latency and FEC targets will be achieved
- Ensuring reliability targets are met
- Maintaining backwards compatibility with previous generations of PCIe technology
- Developing protocol enhancements to improve bandwidth
- Continuing to emphasize techniques to reduce power
