I'm concerned about the "full load" case, where power management should
not have any noticeable impact, I think.

Aha! That's more worrisome.

Oh, regarding which sensor is used, IIUC they use "the APU internal
sensor" which would be either k10temp or radeon's sensor, both of which
return pretty much the same temperature anyway (at least in lm-sensors).

Hmm... so they may see incomparable values even though it comes from the
same sensor as the k10temp?

Either things have changed, or it simply depends on which technician you
happen to talk to.
