If it was a microcode bug to begin with, fixing the bug wouldn't need to degrade performance. If it was e.g. a bad sensor, that you can "correct" well enough by postprocessing, it doesn't need to degrade performance. But if it's essentially incorrect binning -- the hardware can't function as they thought it would, use microcode to limit e.g. voltage to the range where it works right -- then that will degrade performance.

This is both a completely untrue statement, and a judgement on a fix that hasn't been released yet.
