I think I found the option responsible for all the "magical" performance improvements from 1usmus.
That same option is also responsible for no VRM downvolt during idle.
It's the "Energy Preference %" set to 0.
Was set to 30% by default, so the processor can hold its horses for brief load spikes.
If you set it to 100% it will be very slow at boosting up. The equivalent of 100% would be EfficiencyMode, if I remember the name correctly, from CBS options.
The UEFI options required by the PP should already be enabled when set to Auto by default.
You can also set the minimum cores to 50% so your most performant CCX is always active, because, as we can witness from the three samples of most performant cores lists, any core from best CCX is faster than any core from another.
At least that's how it happens on my system.
Slow CCX cores are mostly Parked during regular use:
I think we should take advantage of our 30 times faster than Zen/Zen+ CPPC (1-2ms), as we can use it to unpark/park cores quickly when needed and load only the fastest cores during regular use.
I get basically the same good results with 50% cores parked most of the time prior to benchmarking.
