PCI-SIG News:
As industry bandwidth needs continue to scale, PCI Express® (PCIe®) technology – the de facto high-bandwidth interconnect of choice for over two decades – is positioned to meet the evolving requirements of the compute continuum. PCIe 8.0 specification is targeted to reach 256.0 GT/s (up to 1 TB/s bi-directionally via a x16 configuration) and is planned for release to members by 2028.
PCIe 8.0 specification is anticipated to provide a scalable interconnect solution for emerging applications like Artificial Intelligence/Machine Learning, high-speed networking, Edge computing and Quantum computing; and support data-intensive markets like automotive, hyperscale data centers, high-performance computing (HPC) and military/aerospace.
PCIe 8.0 Specification Feature Objectives
- Delivering 256.0 GT/s raw bit rate and up to 1 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
