@Mieze and @MaLd0nI did some extensive testing with the Bios PL1, PL2, P-Core freq. as well as PL2tau settings and have come to the conclusion, that in my particular environment, the cooler I am using plus the ambient temperatures under which this new Alder Lake build is operating, setting PL1,PL2 as well as PL2tau to Auto, with the P-Core frequency at 4.9 GHz. yields a Cinebench R23 result of 21087 points, with which I can live with. The cooler I am using is an age old Noctua NH-14D with a NSPR (Noctua Standard Performance Rating) of 161 combined with a Noctua Intel socket 1700 adapter bracket. An NSPR of 161 is ample, according to Noctua's database, for cooling an i7-12000KF CPU without restriction, even allowing overclocking, which I am presently not really interested in. CPUFriend as well CPUFriendDataProvider were both enabled, in the applicable Kernel --> Add config.plist section with the -ctrsmt boot flag also active, when the Cinebench R23 21087 points performance value was achieved. I believe it to be superfluous to tinker with the PL2tau duration when both PL1 as well as PL2 are set equal ie. 190W, 190W or whatever wattage. The rationale behind my thinking is that when the PL2tau time in seconds that PL2 is allowed to be active in its set power, lapsed, bios is then supposed to toggle to the power setting for PL1, which when that also equals PL2, makes no sense to me, it's sort of nothing gained nor lost, for me therefore a non starter to begin with. Should my interpretation be wrong then kindly enlighten me on this issue. BTW I am aware that macOS is unable to differentiate between P and E cores for the CPU under discussion because Apple never used an Alder Lake cpu in any of it's recent opsyses, this could also, at least in my humble view and limited understanding of the subject matter, lead to performance evaluation software getting confused in generating consistently reliable outputs, as you are indeed experiencing, especially when E-Cores are mistakenly treated as though they are P-Cores, by the evaluation software used. Just my 2 cents. Greetings Henties
