How does the latest Win10 Update determine which CPU core is better than others? It's supposedly one of the coolest new Win10 features.
If you use optimizations in UEFI/BIOS and Windows to prevent prevent cores from fluctuating/boosting, forcing fixed clocks, does the good/bad core feature even make a difference?
I don't think it does, in performance at least. If each core gets its own voltage, which seems to be the case (the actual power/voltage delivery regulation inside the CPU is very complex and sophisticate, would be nice if anyone knows more details), then the best core might use slightly less voltage to reach the 5GHz. Probably completely irrelevant in practical terms. This being said, outside gaining a few more seconds on intensive tasks like encoding/rendering, and getting a bit better FPS in some games (most modern games at Ultra @1440p should mostly be GPU bound even with the 2080ti), you don't really get much from the OC. The 8700k is already boosting to 4.3GHz by itself, on all cores, and it's also extremely snappy to the point where you just won't see any difference. Locking it at fixed voltage and clocks will just kill its power efficiency for pretty much no gains outside the few exceptions.
