I was amazed at how much power the interconnect was taking on these parts. Even with all the other downsides I was convinced it was the right move, but those power requirements are giving me second (third?) thoughts.
The 7nm parts (incl. Ryzen on up) are rumored to use 16-core CCXes, so we should see 64-core EPYC and possibly Threadripper with no worse IC power use. Hopefully they'll make the IC better as well.
7nm EPYC being fabbed on TSMC does give some chance for a big monolithic die. TSMC has a long history making large dies and their 7nm process should be mature enough for decent yields at that point. I am speculating out of my depth, though.
