AMD Ryzen 9 9950X3D and 9900X3D to Feature 3D V-cache on Both CCD Chiplets

The wider the frequency gap the less consistent OS feels and behaves in terms of P cores and E cores. I'm sure it's true of individual P cores as well. Consistency matters you can't have crazy amplitude differences and expect smoother consistency.

My comment is in reference to just p-cores. Windows will over load the 2 cores at 5.4ghz, and the 5.3ghz cores get much less load in thread heavy software. Down clocking so all cores are at 5.3ghz fixes it completely.

AMD has a much easier fix though, I think there is a bios option that disables preferred core scheduling. With these new chips I would then (if AMD dont do this automatically) just make sure games have an affinity configured to use one CCD so will always hit cache.
