It seem to be HWP enabled with FakeCPUID 0x0506e3, xcpm is always on base on this CPU ID.I have build my Mac with kaby lake cpu, i7-7700k.
when open some app, and put in idle
room temperature, 21.5c
using ssdtGen.sh, and put SSDT.aml in acpi/patch
power jump in 5.8w~11.98w, IA 3.3w~9.7w
frequency 1.96Ghz~2.69Ghz, GT, 0Ghz

which one is best ? may be average is same.
Same issue as my i3-7100 & Pentium G4560 but no problem with my old CPU Pentium G4500 (Pentium Base CPU xcpm function only work on El Capitan not Sierra)
XCPM seem to be function incorrectly on Kabylake CPU with HWP enable , unlike Skylake CPU can function properly with both HWP & XCPM enable.
Now I only enable HWP function which is much better than XCPM.
For HWP fully function, need disable xcpm (not disable -xcpm boot flag).
