I wonder if it Windows 10 changing behaviour in recent major update. I am using Windows 10.0.10586. I am well aware of TurboBoost that mentioned in this SuperUser question. My CPU could hit 2.70GHz in single core mode as specified in the documentation.
However, it's rather a no brainer as earlier in Windows 8.1 I never hit more than 2.40GHz. Is it Microsoft changing behaviour to milk more power or something else? - if it something else, I suspect Intel Dynamic Platform & Thermal Framework driver is actually involved.
Anyway, I need some insight.
