> it might simply be as rebadged and slightly nerfed EPYC chips
Well, that is what first-gen Threadripper was. Same socket and all, but with half the connected DDR lanes and a pin telling the motherboard it's not EPYC.
The first-gen Threadripper only had two dies, and even the WX series was a bit weird internally, with two of the four dies not being able to perform IO.
I know it's not a big difference, but given the changes to IO and the 16 core consumer version, I don't see why there would be any internal difference to EPYC this time around (which this article claims will have a variable number of chiplets).
