But how does it compare to Safari on Apple computers? AFAIK Safari is extremely power efficient.

That's really an Apples to Oranges comparison since Macs and PCs aren't comparable. Yes you could run Windows in BootCamp but it isn't tuned for that and is actually hampered. It would be like making a Surface Pro a hackintosh and using that as a basis for comparison.

  > you could run Windows in BootCamp but it isn't tuned for that and is actually hampered How is bootcamp'ed windows hampered? It works perfectly fine for me. In fact, it's better than many Windows laptops I've used because they almost all ship with so much bloatware on them.

    The HW has proprietary power management features that Windows cannot take advantage of. For the end user it's probably no big deal, but I think the commenter you replied to is right - power management is a delicate dance between hardware and software, and not all hardware is accessible from all software on every platform.

      "Can't" and "won't" are distinct; if Apple doesn't want to write e.g. Power Nap drivers for Windows, Microsoft could certainly do it. (I'm surprised they haven't; Windows has the incentive to work well everywhere much more than Macs have an incentive to run everything equally well.)

        Could they? Do they have access to the Apple firmware documentation?

        What would they stand to gain? This is what .001% of it's users?

      This statement is true for any laptop running Windows, it is not MacBook specific

        Dell has a vested interest in making sure Windows is as battery efficient as possible on their laptops. Apple does not. Base line Windows power management (generic Intel drivers, etc) is probably good enough for them.

  Comparing Edge on Windows to Safari on macOS is apples to apples. Browsers running on an OS. I d be really interested in this comparison, since Apple's big selling point is being apple to specialize since they control the hardware. If Edge can come close or beat them on more diverse hardware, that would be very impressive.

    Not quite. I imagine Windows isn't well optimized for a MacBook Pro, Apple isn't going to go out of their way to squeeze every drop of efficiency out like they do on OS X.

      The MacBook Pro is standard x86 hardware nowadays using off the shelf parts available to most manufacturers (except maybe the chassis and display). Do you know if there's something else special about them?

        I know that in order to use the following you must install Apple's Support Drivers on your Windows Image. * USB 3 * USB-C on the MacBook (Retina, 12-inch, Early 2015) and later * Thunderbolt * Built-in SD or SDXC card slot * Built-in or USB Apple SuperDrive * Your Apple keyboard, trackpad, and mouse Assuming BootCamp were just a hyper-visor exposing the underlying hardware or a HAL, why are custom drivers necessary for those things?

Well half the things on the list Apple announced they were doing like 2 years ago

There has been a lot of similar work on iOS. Check out the WWDC videos at developer.apple.com a year or more likely two back. It is quite amazing what can be done by schedulers and proper use of resources. I guess these optimizations have also found their way back into macOS and Safari on the laptop platform. Considering the release frequency who knows for sure but at least Apple claims their broswer is very efficient. It is worth noting that some of the changes go really deep in the architecture and are not easy to pull off. I think lack of system level focus on low battery and the need to do deep changes in the OS are the reasons for the considerable lateness of Microsoft on this front.
