So there max frequency is correct. That can be 5.5 GHz or 5.4 GHz. CPU 8-19 are Efficient cores There max can be 4.6 GHz, except CPU 12, 13. 4.6 GHz also match the spec. The max perf raw value is 65. That is also correct. The nominal freq of all is 3300 MHz, that is also correct for all. Except for CPU 12 and 13 the nominal perf is 46. I expect that nominal perf value of 12, 13 should be same as other efficient cores. But here it is not same. Let me check if I can find some contact of Asrock to see why is this case.
