What does "CPU Package" do?

Recommended Posts

After analyzing the behavior of the "CPU Package", it seemed to reflect the highest current temp of the hottest core. Now I'm not so sure.

"CPU Package" is one of the temperatures that Intel processors measure using their integrated on-die temperature diode.  Only Intel knows what exactly does it measure and how.

It's the highest temperature among all diodes on the CPU (cores, GT).

 

mumak, thanks for your comment. But taking Fiery's definition and your statement into account together, I must logically resort back to my original assumption: that "CPU Package" reflects the hottest core on the board. But if you look closely at my above attached photo, you can clearly see that this must not be the case. And what other diode(s) on the die could be hotter than the Core itself (that the core Diode is measuring)?  If what you are both saying is true, what am I missing here?
