will just be highly binned 13900ks. basically anyone right now buying a 13900k is getting the bottom crap of their pile.
Can't see it, that'll not be even a 5% performance increase. Even the dumbest guy at Intel would surely realize it'll be a huge flop and won't compete with Zen43Dcache.
I think it'll need to be either:
1. Further improved 10nm process, with at least +200Mhz over 13900KS (so 6.4Ghz turbo)
2. Extra cores. Perhaps they can tweak the design for 10 or 12 P cores? Extra E cores would be boring at this point.
