I upgraded to a i7-8700k from a i7-7700k. I spent the weekend trying to get the system up and running and tuned. I have noticed amazingly low Package TDP reading. Core Temp and XTU agree so I don't immediately feel I have a faulty reading.
For Example, Average Package Readings set to 4.9GHz all Core around 1.355v reading. I am using the XTU recent average over the last 30 second period of the test.
Idle: 11W, 0.780v
Cinebench: 78W, 1.315v
CPU-z Stress: 53W, 1.315v
Geekbench 4: 17W, 0.998v
x265 Encoding x2: 73W, 1.340v
(That is two software x265 encodings at the same time that hammer the AVX2)
Time Spy: 23W, 1.203v
My System:
System
Intel i7-8700k (delided, liquid metal)
EVGA Z730 FTW
Corsair Vengence DDR-2400 (hold over)
EVGA GTX 1080ti SC2 Hybrid
HP EX920 1TB NVME
Corsair HX750
DeepCool Genome II with 360mm AIO
I choose the EVGA Z370 FTW based off of Toms Hardware Review, that showed this board running VRM temps at about half the competition and much lower current draws as well.

Looks like I actually am running a bit higher voltage than my old set up. I have several questions.

I thought that the Coffee Lake Chips broke TDP ratings
Are my readings just junk?
What is going on?
Am I just lucky?
