On 65nm and 45nm there are multiple DTS sensors on each core located in all potential hot spots, ie DTLB, L1, IntReg etc. DTS logic scans them and only reports the hottest one as core temp. See intel slide in old post below. So the i7 sensors are not "closer to the core" and even if more optimal placement occured it might be a couple C, not 20C difference. It is architectural differences, TDP, leakage, IMC, power density, etc.

On the other hand, I agree with what you said about stress testing, it is your daily computer use where temps are most important.
