PCIe 8.0 draft spec targets 1 TB/s bandwidth, new connectors

By PulseAugur Editorial · [2 sources] ·

The PCI-SIG has released the first draft of the PCIe 8.0 specification, targeting a bandwidth of 1 TB/s through a 256 GT/s transfer rate. This new standard will incorporate PAM4 signaling, FEC, and Flit Mode encoding, while aiming to maintain backward compatibility. Hardware designers can now begin prototyping, though some aspects of the specification are still subject to tuning before final ratification, expected in 2028. AI

IMPACT Increased bandwidth for PCIe 8.0 will enable faster data transfer for AI accelerators and GPUs, potentially improving training and inference speeds.

RANK_REASON This is a significant industry development as the first draft of a major hardware standard, PCIe 8.0, has been released, enabling hardware designers to begin prototyping.
