The only company that can achieve that kind of efficiency is Apple. I say this as a proud Apple hater.
It is not about efficiency, we already know for some time that x86 is not really efficient compared to newer architectures like arm and risc.
But no other ecosystem exists that can force such an architecture move without much much more problems.
So i would rephrase it as "The only company that can force that kind of fundamental change on its user and developers is Apple"
I am not saying it is a bad thing (just alone the rosetta translate layer is actually really impressive). Would love to have some actually good and mainstream arm options such as Linux Laptop.
Microsoft is trying the same - but royally screwing up how they deal with hardware partners. Performance wise the snapdragons they use are roughly a decade behind what Apple is doing - I have both systems for work projects.
The x86 emulation in Windows is imo better solved than rosetta - but the rest of the stack is a mess. For example, the deployment tools only got arm support a few months ago.
And Linux support on those things sucks - while using it on the M1 is great.
Snapdragon Elite is going to be a rather sizeable step forward, thanks to the Nuvia purchase. Windows on ARM exclusivity is also going to end in 2025, and apparently both AMD and Nvidia are going to have chips ready. I'm hoping Lenovo and/or Dell will put some effort into Linux support once we have better chips, and that the likes of System76, Framework, and Starlabs are able to release ARM models.
Apple silicon is in no way a 'quantum leap' over anything. Even arm's general efficiency in low power situations diminish as it enters ultrabook territory
AMD can compete in performance and power/Watt mid to high load, but is shit with low load efficiency. intel has nothing at all. Apple scales nicely over the complete range.
If you want a relatively small notebook with lots of RAM you also don't have options (not really AMDs fault, but hardware manufacturers seem to produce mostly shit now). Framework is pretty much the only somewhat decent option with 64GB max, if you want more there's pretty much only apple - which is way overcharging for that.
Mobile workstation. There are some Xeon notebooks which also can take more than 64GB - but they have bad availability, cost about the same as a high end mac book pro, are significantly larger and heavier, run hot and have shitty battery life for comparable performance.
The overall hardware situation has been ridiculous for many years now. I recently got a new Dell Latitude for a customer project - runs hot, performance and runtime suck. Runs out even faster than my tiny GPD pocket 3, while providing worse performance. Compared specs - they indeed stuck a smaller battery into the business notebook than into the portable toy. We're now at a point were a Chinese niche hardware maker does better thermal management for x86 systems than any of the established manufacturers. Current AMD mobile CPUs are great - and I'd love to have a good notebook with one, just nobody bothers building it.
The entire concept of "quantum" is that it's the smallest possible unit.
A "quantum leap" is the smallest measurable change in electrical charge.
The Planck length, based (it's a long story, links below) on that smallest possible charge, is around 1.61×10−35 m. (That's 0.00..00161, with about 31 more zeroes). Which is about as much societal/technical progress as I think Apple has made.
