There are no official reviews yet, but the consenus is, that these will take an insane amount of power to run (worst problem) and require an insane amount of cooling (just as bad). I will say that I think this "pre-review" is essentially what everyone will say in a week IMO, but if I am wrong, I will eat crow.
I say it will be close to the 3900x in performance, and have a higher street price, and take WAY more power and cooling. That is a prediction, and an opinion, just leave it at that.
Can you please provide data which supports "consensus" (majority rules, based on a poll +/-) that these will take an "insane" amount of power"?
