Active core tuning is a turbo bin setting. It means you’ll see the 1 active core multiplier when the system is using 1 core, which almost never happens. The 4 core bin is the most sane, because that’s how windows usually works shuffling threads arounds.
Your xtu shows you can set a per core multiplier. So set your best core to the multiplier you want (61), and set the rest lower if you want a safe 1 core boost.
If you go into the bios and only enable 1 e core per group it should be the same in theory, problem is how to set the affinity in windows without APO. Maybe turning off hyperthreading will force it to work if a game needs more than 8 threads.
This has nothing to do with apo.
You need multiple clusters of E cores for it to even do anything. Basically APO uses one e-core per bank of 4 to maximize L2 cache for a game thread (l2 is shared by 4 e core clusters). So the only 12th gen cpu that will get meaningful performance is the 12900k. That means it only makes sense on processors with 8 or more e cores.
60fps is pretty pedestrian these days. Once you start gaming with higher framerates in mind, the newer cpus make a lot more sense.
