The official first draft of the PCIe 7.0 specification (version 0.5) has been announced and is still expected to be fully released next year

News from this site on April 3, PCI-SIG, the PCIe specification development organization, recently announced version 0.5 of the PCIe 7.0 specification, that is, its official first draft has now been released to PCI-SIG members.

Compared with the PCIe 6.0 specification released in early 2022, the PCIe 7.0 specification doubles the rate again while continuing to use the PAM4 signal modulation method, which can be achieved 128GT/s raw data rate and 512GB/s bidirectional bitrate in x16 configuration.

Development of the PCIe 7.0 architecture focuses on improving channel parameters, coverage and energy efficiency, targeting 800G Ethernet, AI/ML workloads , providing scalable interconnection solutions for data-intensive applications such as hyperscale data centers, high-performance computing, quantum computing, and cloud.

The PCI-SIG Association stated that based on the current development progress, the official version 1.0 of the

PCIe 7.0 specification is still expected to be launched within 2025.

According to inquiries on this site, industry company Alphawave Semi has launched PCIe 7.0 signal generation and measurement technology products earlier this year.

For consumers, the PCIe 7.0 specification is even further away. Currently, consumer-level platforms are still stuck at PCIe 5.0, and no PCIe 6.0 products have yet been released.

The above is the detailed content of The official first draft of the PCIe 7.0 specification (version 0.5) has been announced and is still expected to be fully released next year. For more information, please follow other related articles on the PHP Chinese website!
