Indeed, as Gregory well mentioned, PGO is unrelated to a particular CPU on which we do profiling.

PGO is unrelated to the particular CPU the profiling is done on. (It is conceivable that it'd make a small difference but I've never observed that in practice)

Does Profile Guided Optimization performance improvements are specific to the chip where the built is done or the performance is better on a larger set of chips?
