I have trouble finding objective flops/watts or similar tests, but subjectively, Apple Silicon is fast, quiet, and long-lasting in a way that no laptop has ever been for me. It's a dramatic upgrade in performance, noise, battery life, and heat vs all the previous laptops I've ever owned or used, including Intel MacBooks, ThinkPads, Surface Books, Chromebooks, small biz machines, gaming machines, and countless others.
"Sweet spot" is exactly right. It's not the best at anything but the best balanced that I've ever used, by a huge margin.
I don't think it's magic either and I hope that Intel, AMD, Microsoft, Google, Nvidia etc. can deliver a similar package in a future laptop. For now though they seem hopelessly behind, at least among the products I've used.
Also, among those companies, Nvidia is the only one I'd trust to do a decent end user experience. Maybe Google to some degree, but they'd end up sunsetting the product after a generation or two.
Microsoft tried to do the same with the Surface line, but every single one I've used sucks. The tablets are way too heavy and clunky. The laptops overheated and couldn't even charge while playing games. Windows has a ton of ads.
Apple's integration of all the things really makes it a standout in today's commoditized and enshittified world, IMO. It's not just tech specs but how the product feels to use at the end of the day.
