I have been trying to figure out the workings of the DTS to understand why reported temperatures is not precise. I read the realTemp guide and some presentations about the sensors from intel. My understanding is this:
Temperatures amongst core on CPU are broadly similar although have differences from the production process with semiconductors. Also, the DTS themselves dont measure a temperature well. Example, perhaps core 0 DTS counts in units of 1.05C whereas the other cores are some other unit maybe 0.97. This does not matter to intel as the design of the DTS was just to measure distance fom TJMax, these small variations in the actual scale of the units does not matter much. The sensors sole job is to safety trip at TJMax. Unit variations make an accurate temp C hard from just using the DTS. Intel seem to recommend using an average from the four cores as the best measure, makes sense given my understanding.
