The PCI-SIG recently announced the next generation of PCI Express - 7.0 - will be released in 2025. We've only just heard about PCIe 6.0 (see this recent podcast), so it's interesting to see that the working group is already committed to extending the performance and capabilities of PCIe further into the future. Chris caught up with Al Yanes (President and Chairperson of PCI-SIG) earlier this year at Flash Memory Summit to get an update. This podcast was recorded after the event and goes into the detail about the improvements. The timeline for PCI Express means we're seeing new PCIe 5.0 devices on the market today, with PCIe 6.0 devices expected in 2025 and PCIe 7.0 supported hardware in 2028. With a certain future for PCI Express, vendors can develop products and have confidence that forward and backward compatibility will be maintained until the end of the decade.
