The original Apple M1's performance per Watt and physical battery size may have been special when it first came out, but nowadays there's nothing special about its hardware specs relative to a modern x86 laptop.
The difference you perceive is mostly software. Windows and Linux are really just designed for desktop machines first and foremost. MacOS was too, but when they transitioned to Apple Silicon, they replaced a lot of the internals with stuff taken from iOS, and iOS is designed with batter life first and foremost.
Getting the level of battery life out of non-apple laptops is just going to be a long, hard slog of going through the operating systems and auditing *everything* and every design decision for how it affects battery life and how much resources its using.
Interesting, I thought Apple Silicon was still ahead on raw numbers, would you mind pointing me at any resources to learn more?
Is that still true when you consider the whole system power consumption vs performance? I was under the impression that Apple's ram and storage solutions give them a small edge here (at the cost of upgradability / repairability)
Apple Silicon has a lead in performance per watt over the competition (not a gigantic one, but a real one nontheless), but we were talking about M1, which is 5 years old now and has no appreciable hardware advantages compared to an AMD or Intel laptop made in the last few years.
The reason an old M1 laptop gets better battery life is almost entirely a software difference.
"raw numbers" always means a lot of things. Apple's CPU benchmarks are neck-and-neck in multicore and usually top-of-class in single-core performance compared to other desktop chips. x86 will draw more power when idling and during bursty workloads, but is typically more efficient during sustained SIMD-style workloads.
The M3 Ultra is putting up some of the saddest OpenCL benches I've ever seen from a 200-300w GPU. The entry-level RTX 5060 Ti runs circles around it with a $400 MSRP and 180w TDP. I truly feel bad for anyone that bought a Mac Studio for AI inference.
