What I'm curious about is, since Epyc will have PCIe 4, will Ryzen? Should be doable without a socket change.
I'm not interested in a platform w/o PCIE 4.0 + 7nm going forward.
EPYC will ahve PCIE 4.0
Ryzen and threadripper better as well.. Otherwise, I have no interest.
PCIE 4.0 needs to be supported by your motherboard.
So, if you want PCIE 4.0, even if the processor supports it and the socket, you're going to need a new mobo.
PCIE 4.0 is backward compatible w/ 3.0.
I have ryzen 14nm/pcie 3.0 purchased in 2017. I need 7nm/pcie 4.0 to get me off this platform.
I am willing to sell off the CPU/Mobo for it as I paid little to nothing for them.
This is sort of why you don't go crazy buying the most high-end hardware of a series. The mid-tier of the upcoming big update series obsoletes it relatively quickly.
Having paid about $100 for a mobo, it's fine if the 3rd gen obsoletes it.
I'd get $50 or so for it. Good deal.
PCIE 4.0 was never going to magically work on a PCIE 3.0 motherboard. So, there is no reason to have any expectations about 3rd gen Ryzen. I'd hope they shoot for much more PCIE slots beyond the current 32 slots offered on Ryzen and PCIE 4.0 and more I/O for threadripper than I care about maintaining an incompatible socket. If they retain compatibility, it should be on 8 cores and less on the budget tier line of 7nm.
I want the platform to soar towards its potential not be restricted by unrealistic backward compatibility.
