Still that score equals a ryzen 5800x (zen 3 16 threads) I mean ok I know that my CPU is faster but that much faster consuming only 7 watts? The r23 bench does not finish instantly it needs some seconds so its not that the CPU just mastered it in a split second and didnt have time to start "draining some juice"5.2 GHz was most likely reached for a very small fraction of time only. Check the average clock and effective clock values, those are much lower.
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)Yes, that's very strange. Check which core were mostly utilized during the test, the E-cores only perhaps?
