Sadly I cannot confirm this for my 6+ different laptops I owned. And I tried all the crazy settings, grub, tlp, .. and even compiling the kernel myself.
It is hard to beat loads of dedicated engineers, who are paid regular and well and have access to all the proprietary device information and even manufacturing.
edit: maybe there was one time, when a linux stock install performed maybe equally than a stock windows install. But that was only because of the windows bloat, which linux does not ship. But I can easily remove most of the bloat, but I cannot just write a better gpu driver. But if windows continues its bloat path, it will be soon inferior despite way better drivers.
