So specifically, Intel have a new chip, and for it they need a new scheduler, that strangely, doesn't know how to pick the best cores.
AMD are also about to make massive steps in the world of l3 3d cache, something intel are incapable of doing, and have recently retired their project.
Both these specific AMD advances are for some reason of unspecified origin B0rked in the release version of windows 11.

AMD Ryzen Bug Confirmed on Windows 11
The issue is a little complicated, but I will try and break it down as simply as I can. – For those of you unaware, AMD Ryzen processors on Windows 10 primarily work by allowing the operating system to pick the two most efficient cores on the CPU (largely the two which can maintain peak speeds for the longest period). These are then given priority status for the vast majority of general workloads.
The problem, however, is partly twofold. Firstly, it would appear that Windows 11 is ignoring the ‘preferred cores’ system meaning that less optimal ones are getting picked. Secondly, though, the L3 cache latency has been found to triple on the new operating system.
Put simply, both AMD and Microsoft have largely agreed that in general use, Ryzen processors are around 3-5% slower on the new operating system whereas the gaming impact could potentially be as high as 10-15%!
