Makes sense for two reasons:
They show everyone that they don’t push faulty hardware, unlike intel and they also delay the launch until after intel push their microcode update to ‘fix’ their high-end models, which will reduce performance. Ryzen 9000 will look even better in day one performance comparisons.
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.

Voltages are probably too high. With lower voltages they very likely won’t be able to hit the same clockspeeds.
It’s not confirmed. Its just pessimism, albeit very well argued and precedented.
