Okay:
1). 20 CU on 7nm? This product shows up on exactly zero of their past roadmaps. AMD has already told us that the first 7nm APUs will show up in, what, 2020? Picasso, a 12nm APU, appears in 2019.
2). The boost clocks seem unrealistic given core counts. I mean, why would you reserve the highest boost clocks for the chips with higher core counts? XFR2 doesn't even have that kind of restriction, and certainly XFR3 won't either. I would expect boost clocks to be segmented between CPUs that feature XFR3 support and those that do not (namely, the non-X parts). I will observe that the exception here is the 2950X of the current lineup which has a listed max boost of 4.4 GHz (as opposed to the 2700x which boosts to 4.3 GHz), but that is more due to the binning of Threadripper dice than anything else. The 2990WX certainly has lower boost clocks than the 2950X!
3). The "base" clocks seem completely ridiculous. 5 GHz base for the 64t Threadripper product? Completely absurd. And really, 4.3 GHz as the base clock for the 3800x seems silly as well.
4). Dual socket for Threadripper? What?
5). XV running @ 5 GHz on 28nm? No.
