I have an m1 mbp and a asus zephyrus g14 of similar vintage, and I have to say day-to-day, stock, the m1 mbp can get better battery life idle, and is less prone to getting into a state in which its fans need to activate. I'd say they can both get over 10 hours of battery life easily which gets into the point where who cares anymore, but it's easier to get the asus to drop to only 5.
But, speed-wise, I haven't noticed a difference. They're both snappy. In fact the asus would be faster for all practical purposes of mine because:
* macos has comically bad UX, it wishes for me to use the mouse far more often than it should, and fights me on keybindings.
* programs like blender and stable diffusion just aren't optimized for apple. they're optimized for nvidia. i can't say if the m1 gpu is actually good, because nobody seems to care to support it, which brings me to my final point:
it doesn't much matter if m1 is or isn't good as long as it's exclusive to apple's walled garden. if I can't put it in my PC, it may as well not exist, both from a user point of view but also support of developers.
The best outcome of the m-line of CPUs would be for hardware competitors to make another great ARM chip, that I can actually use elsewhere.
