Fair enough, but its probably also less of a drop than what the firmware would automatically do the moment it hits max temps without thermald

I think that's misleading. P-states themselves adjust voltage and
frequency, so performance can be impacted by them alone. T-states
essentially lock the CPU even further through clock gating. So the
documentation seems to be implying that the daemon was able to reduce
temp just through p-state adjustment and not resort to t-states would
would have impacted performance even more. In other words, it was
able to reduce temp while limiting performance loss but not eliminate
performance loss all together.
