Just found that it has some new class, something like this.
Specify the minimum number of unparked cores/packages allowed for Processor Power Efficiency Class 1 (in percentage).

And also it finally allow parking more than half of the CPU as default. ;)

I will continue to check for it after exam...

PS:Poor cpu, only left 1 core to run. ;D
PS2:Reminder for myself to test WinRaR for new core-parking

Well, it is disable as default in Windows 8, but enable in Windows 10.
I guess they want to having better power save and aggressive Turbo frequency for Intel and AMD, but it need some test or research to prove that first. :)

To update this thread: As I posted in an article, Intel's newer CPUs move control of core parking to the hardware (https://bitsum.com/product-update/intels-speed-shift-validates-parkcontrol-and-process-lasso/) because Windows did such a terrible job of it. This validates the idea of dynamically disabling core parking in its entirety in previous architectures.

Yup, and better performance and power save compare to OS managed core-parking enabled too. ;)
This might also improve the overclock performance, but I am not sure about this one, might want to read some overclocker result. :)
