the drawing is pretty accurate i think, except that i think win11 only will assign p cores to an app that doesn't specifically ask for something else and use the e-cores for OS level tasks. i could be wrong, but this would avoid most issues with software that's not specifically geared to exploit both.
you can also manually choose which cores buzz uses in preferences / engine, it would be interesting to see what happens if you do that, do the e cores even show up there?

thanx temporalsounds and UNZ for links and explanaitions. :)

OK, you could use BUZZ with W11. Hmm, actually my plan was to change OS at the end of support in 2025. But if I buy a new PC I have to change perhaps to W11 earlier. I wait defiitily for Ryzen7000 and DDR5 this year and the some price drop. We'll see... how far carrys may old PC...

Yes, would be nice to hear here from a user who uses BUZZ on AlderLake and how the cores behave.

ok. Installed Buzzx64 2022 edition on AlderLkae 1260P machine. All cores "show up" in preferneces !?
EDIT: I should probably deactivate Hyper Threating. 4+(4)+4 cores shown in buzz prefs out of 4p + (4) +8e cores?

but cores do not performing high, some cores change from active to parked.

Interesting, i guess that sort of makes sense since all the cores on this CPU at least support the same instruction set (AVX2) and they have disabled AVX512 for now anyway. How efficient windows will schedule work on those cores (especially under load) remains to be seen, but at least it seems do some kind of juggling.
