> All that to say: M1 is pretty fast, but the reason the battery life is better has to do with everything other than the CPU cores. That's what AMD and Intel are missing.
A good demonstration is the Android kernel. By far the biggest difference between it and the stock Linux kernel is power management. Many subsystems down to the process scheduler are modified and tuned to improve battery life.
And the more relevant case for laptops is macOS, which is heavily optimized for battery life and power draw in ways that Linux just isn't, neither is Windows. A lot of the problems here can't actually be fixed by intel, amd, or anyone designing x86 laptops because getting that level of efficiency requires the ability to strongly lead the app developer community. It also requires highly competent operating system developers focusing on the issue for a very long time, and being able to co-design the operating system, firmware and hardware together. Microsoft barely cares about Windows anymore, the Linux guys only care about servers since forever, and that leaves Apple alone in the market. I doubt anything will change anytime soon.
