So far it does run really well.
I can't say you much, how it does run against acpi powersave, since did not used often powersave.
Actually, I have in my head how the amdpstate powersave does run, at this one runs very awful in my eyes.
It seems that the epp pstate runs differently, I use most time power preference. EPP seems to have a better PPW (powerperwatt) ratio and it does scale really well.
The performance from pstate epp power is actually equal to acpi performance / pstate performance.
Here you can find some more info's and some comparison:
