To put it simply, I don't think we'll get anything closer to the M1 on the x86 architecture.
You'll have to wait for Framework to offer a Snapdragon instead of Intel/AMD but they haven't announced anything yet.
The first-generation Intel Ultra lineup is comparable to the M1 and M1 Max. See: https://nanoreview.net/en/cpu-compare/intel-core-ultra-7-165...
Intel's integrated graphics aren't as good, but they are similar in terms of power consumption & CPU performance.
Compared to M4, well, that's a different beast entirely. I'm not sure what's the latest there.
I don't follow CPU news and have no idea what lake they're at now, but I'd be surprised if Intel and AMD didn't have a chip competitive with an M1 by now.
When I google "fanless amd intel laptop cpu" I find this old thread https://www.hackerneue.com/item?id=31142209 which does suggest some fanless machines exist. That's from 3 years ago so surely there are even more options today, no?
