Qualcomm's stuff is within single-digit percentage points of the current-gen AMD and Intel chips both in power usage, performance, and battery life

Back in June, the new Snapdragon X processors were a lot more efficient than their x86 based counterparts. I can personally attest to much lower levels of heat generation.

The problem is that the current tradeoff is that huge amounts of the software you've been using just does not work, and a huge portion of it might NEVER work, because nobody is going to invest time in making it behave.

I agree with the sentiment, but IMO this is a PC and Windows problem. I would also extend this beyond pure comparability. I say this for a few reasons

• I lose about 5% charge/day with my laptop asleep. It does wake up very quickly, but 5%/day feels like a lot. At this point, I don't think Microsoft has a strong incentive to really optimize the kernal for efficiency
• Historic massive variability in hardware across devices also makes it hard to optimize efficiency, although the current crop of snapdragon x laptops seem to have less variability
• One of the strengths of windows is that it can run applications written 20+ years ago fairly reliably. There's a ton of software that's still floating around that hasn't been actively supported in years. I don't see all of these software companies desiring to port their code over, especially without guarantees that the market will adopt ARM (the Apple approach) or until they see the ARM adoption rate go up (the current Windows approach)

All that said, I've had zero issues with emulation so far. I never personally used a M1 max when they launched, but from reports of that era the current Windows experience is at least as good as that.
