PCI-SIG Announces Release of PCIe 7.0 Specification
PCI-SIG has officially released the PCI Express (PCIe) 7.0 specification, achieving speeds of 128.0 GT/s. This new specification is aimed at data-driven applications such as AI/ML, 800G Ethernet, cloud computing, and Quantum computing. Work on the PCIe 8.0 specification is already underway to continue supporting industry investments and product roadmaps in the PCIe technology ecosystem.
PCIe 7.0 Specification Features:
- Delivers 128.0 GT/s raw bit rate and up to 512 GB/s bi-directionally via x16 configuration
- Utilizes PAM4 (Pulse Amplitude Modulation with 4 levels) signaling and Flit-based encoding
- Provides improved power efficiency
- Maintains backwards compatibility with previous generations of PCIe technology
"PCIe technology has been the preferred high-bandwidth, low-latency IO interconnect for over twenty years. We are excited to announce the release of the PCIe 7.0 specification, continuing our tradition of doubling the IO bandwidth every three years," said Al Yanes, PCI-SIG President and Chairperson. "As the demand for artificial intelligence applications continues to grow rapidly, the next generation of PCIe technology meets the bandwidth needs of data-intensive markets deploying AI."
"It's a significant milestone when a PCIe specification reaches its final version," noted Ian Cutress, Chief Analyst and CEO of More Than Moore. "The demand for compute and networking, enabled by PCIe technology, is at an all-time high. Datacenters are ready to deploy networks based on PCIe 7.0 technology, and many ASIC companies are already engaged with IP providers to take advantage of this new specification."
