PCIe 6.0 spec just months away from completion, doubles max data transfer rate


Re: Fine, provided ...

Not quite - the speed stays at 32GT/s but the physical and data link layers are quite different in Gen 6. PAM-4 signalling, error correction, fixed packet sizes etc... However, the intent is to still interoperate with older systems.

We are only just seeing early samples of Gen 5 devices so that will not become mainstream until 2022. I can't see Gen 6 making a real impact for a few years - this cycle could be much longer than the 18-24 months we normally see
