Yes, that's very strange. Check which core were mostly utilized during the test, the E-cores only perhaps?
All the cores were utilized, but again it wouldnt make sense simply because of the score, I mean lets consider what you asked me (only the 8 E-cores being utilized)
How is it possible for the E-cores only to be as fast as 16 threads of a 5800x? (it wasnt an exagerations that's how much a 5800x gets on cinebench)
And ok lets asssume that the E-Cores alone are equally as fast as the 16 threads of the ryzen, are they so fast while only consuming 7.5 watts?
If that was true it means that the 12900K a) is the most efficient CPU in the world even compared to an apple M1, b) that the 12900K is like 3 times faster or even more compared to a 5800x and again I know it is faster, but surely not that fast... I think the most plausible explanation is that there might be a bug with hwinfo reading the package power consumption of alderlake (maybe due to the e-cores being new tech? ) or at least being buggy if an alderlake has low custom set PL1/2 values
