Intel Mac is slower in MacOS

As you may know I have got Macbook Air 11 inch, installed Windows 11 on Bootcamp.

So I just have run several Geekbench tests on the machine for both Windows and MacOS

Here is the result

Windows 11 with power cable on

Mac OS Big Sur with power cable on

MacOS is slightly faster but not big gap but almost the same. making sense as it’s the same hardware.

then on battery…

Windows11 on Battery

Mac OS on Battery

um… yes ? Multi core performance is…. quite worse in MacOS…?

That’s something I don’t get. I have run the tests under almost same condition, no applications working at the same time.

Is it the reason why Apple has escaped from Intel cores ? (conspiracy theory lol) .
