In many of the benchmarks linked in the OP and in my comment, particularly gaming benchmarks, the high-end SKUs show results that are significantly worse than would be expected considering the raw performance of the CPU cores and the performance of lower-end or previous-generation chips on the same benchmarks. The problem appears to be due to the Windows 11 scheduler doing an especially poor job of deciding how to schedule threads onto the processor's 2 dies. This generation has particularly high latency between the dies, so if an application does a lot of inter-thread communication and Windows spreads those threads across cores on different dies, application performance suffers significantly.

It's probably something that will be fixed soon with software updates, and Linux fares much better. But the result is that launch-day benchmarks are much worse than they "should" be.
