unpossible

x64 chips can run at 4-5 GHz because these are desktop parts that can drop 10+ W sustained on a single core if need be. Power-frequency scaling tells us that of course this is very inefficient (perf/W), but efficiency isn't all, sometimes you just gotta go fast.

> Either way, put the same chip in a Macbook and in a Windows laptop and the Windows laptop will run hotter but with better performance.

The Windows laptop can't possibly run hotter than a Macbook, all of which reach the throttle temperature (~100 °C) almost instantly.

I actually agree to the artificially limited performance, artificially worsened thermals theory. The Macbook Air design is extremely fishy.
