I have a funny feeling we won't see X670 unless there's something in the Zen 3 redesign that will necessitate a change somewhere. The board vendors have put in all the work for PCIe 4 capability and a lot of the VRMs are built like tanks. What else is there to actually do?I'll stick it out with my X470 board and see what X670 has to offer.
I think we may see a X570 refresh with an improved PCH chip (i.e. 7nm shrink with no active cooling; call it X570X like Intel have done with X299), but beyond electrically linking more lanes between the PCH and CPU I honestly can't think of anything that could warrant an actual new chipset. This is also why I think B550 is taking forever and a day because if you're limiting PCIe 4 to the 1st PCIe slot and the M.2 connected directly to the CPU, what else is there to actually bolt onto the rest of the board?
Edit: I just remembered that the TRX40 boards have nowhere near as many PCIe retimers which is where a lot of the X570 expense comes from. So that knowledge and engineering improvement could be big enough to warrant a X670 moniker.
