AMD delays its Ryzen 9000 launch due to unspecified quality issue — new launch in August; chipmaker pulls back all units shipped globally for quality checks
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.
