I don't think Intel is more efficient if their desktops and this one link is anything to go by
https://www.cpu-monkey.com/en/cpu_benchmark-cpu_performance_per_watt
But I'm not up to date on laptop stuff at all so might be wrong
That's under load. At Idle (which is where your average home PC will spend most of it's time) I think Intel has the edge still.
It's certainly a consideration for a battery device. Watching a video reading emails or staring at a spreadsheet will likely have better battery life than a similar spec AMD device.
We've reached a point where most everyday computing tasks can be handled by a cheapo N100 mini PC.
Actually AMDs mobile parts are pretty good at idle power consumption and so are their desktop APUs. Their normal CPUs, which use the chiplet design are rather poor when it comes to idle power consumption. Intel isn't really any better when compared to the monolithic parts at idle and Intel CPUs have horrible power consumption under load. Their newest CPUs are better when it comes to efficiency than 13th and 14th gen CPU, bus still don't match or even exceed AMD.
I would have to ask for a source on that. I can't really find anything comparing many cpus.
However this video compares top end models on otherwise pretty much identical laptops and amd definitely wins in YouTube playback on battery https://youtu.be/X_I8kPlHJ3M
But if you've got anything to better compare I'm all ears
It may well be the case that they're similar or even swapped now. I can see that the N100 is pretty low power compared to the newest low end AMD chips, but then the AMD chips are better in terms of what they can do.
This one reckons they're pretty similar.

This one reckons Intel are better.

I doubt there's much in it either way. Even if AMD are ahead now, laptops don't get replaced right away, normies replace shit when it fails or is too slow to run whatever shit Google shoehorned into Chrome this year, and the most popular laptops are probably the ones with the lowest sticker price.
