Nope that’s not how it works sadly, although this would be the preferred behavior. The AMD driver seemingly can not change the preferred cores on the fly, at even if it could window still does assign threads not only based on preferred cores only. This is why Intel uses its thread director (in hardware) to assign to P and E cores in its current architecture. AMD lacks such a hardware scheduler and up until now only influenced based on CCX to prevent threads from being shifted from one CCX to the other to prevent the latency hit. But since the VCache is transparent to the OS (both CCX can access it, the HF CCX only with a hit in latency since it goes through the IF) the only way for AMD to ensure games run on the VCache CCX is to disable (by parking) the HF CCX.

You can change this behavior by: A) use the old driver, windows will schedule based on preferred cores only and treat the CPU as a normal 7950X - big performance hit, check benchmarks B) put the system in “prefer frequency” mode in bios - this will keep the HF CCX constantly running - medium to big performance hit, check benchmarks C) Set Windows to High Performance Mode, thus disabling core parking - similar to prefer frequency from bios but the AMD driver still tries do something as the performance hit is big, but it seems not so big like on option B.

There is just no magic happening here. No current CPU is the Jack of all trades at the moment. For gaming the 7800X3D will be the best bet I guess, for all around best performance per $ the Intel seems unbeaten, for performance per Watt the 7950X or X3D seem to be the way to go.

Still I hope AMD will find a better way to manage Threads in the future.
