PCI Express 6.0 With 256GB/s Coming in 2022 Because Screw Bandwidth Constraints
The PCI-SIG announced that it’s already begun work on PCI-Express 6.0. If you’ve followed recent news about PCIe 4.0 and 5.0, this may seem like absolute overkill. PCIe 4.0 isn’t quite in-market yet, PCIe 5.0 won’t arrive until 2020 at the earliest, and now the PCI-SIG wants to finish PCIe 6.0 by 2021. Given the typical 12-month time frame for adoption, that would put PCIe 6.0 in-market by 2022.
