PCI-SIG Releases PCIe 7.0 Specification for AI and Data-Intensive Applications

PCI-SIG has announced the release of the PCIe 7.0 specification, offering 128.0 GT/s transfer rates to meet the demands of AI and other data-driven applications.

PCI-SIG has announced the official release of the PCI Express (PCIe) 7.0 specification, which achieves transfer rates of 128.0 GT/s, announced in a press release. This new specification is designed to support data-driven applications such as artificial intelligence, machine learning, 800G Ethernet, cloud computing, and quantum computing.

The PCIe 7.0 specification delivers a raw bit rate of 128.0 GT/s and up to 512 GB/s bi-directionally via a x16 configuration. It utilizes PAM4 (Pulse Amplitude Modulation with 4 levels) signaling and Flit-based encoding, providing improved power efficiency while maintaining backward compatibility with previous PCIe generations.

The release of PCIe 7.0 is part of PCI-SIG's ongoing efforts to double IO bandwidth every three years, ensuring that the technology meets the growing demands of data-intensive markets. Pathfinding for the PCIe 8.0 specification is already underway to continue supporting the industry's investments and product roadmaps in the PCIe technology ecosystem.
