I’ve been following the Intel story closely. Watched the Gamers Nexus vids. Did I miss it or has it been reported that microcode updates will definitely degrade performance?
Yup, the “fix” seems to be to limit boost to 5.3GHz or so, and there may be other mitigations as well. If it has anything to do with branch prediction or other eager optimizations, we could see further degradations like with the fixes for Spectre and other attacks.

It’s not confirmed. Its just pessimism, albeit very well argued and precedented.

Voltages are probably too high. With lower voltages they very likely won’t be able to hit the same clockspeeds.
