Desktop PCs have only been supporting the PCIe 5.0 interface for a couple of years, and the first PCIe 6.0 SSD appeared just last month, but progress waits for nobody. To that end, electronics consortium PCI-SIG has announced the specification goals for PCIe 8.0, proving that the relentless drive for doubling the data rate with each version continues unabated.
Before you ask, PCIe 7.0 hasn't been skipped or anything like that. In fact, the specs for that version were only just finalised in June of this year. In other words, all the details about how PCIe 7.0 will work are now complete and won't change. With regards to PCIe 8.0, though, all that's been fundamentally agreed upon so far is the data transfer speed.
