Intel celeron N150?
I mean, yeah, technically it's got more ram, but that's literally the only thing going for it. I've got a mini-pc server with that exact CPU. It's good enough for what I need it for, by my wife's 5 generation old M1 Air from 2020 trounces it several times over in terms of speed, even with 8GB.
I mean, if that fits your use-case, I'm not gonna tell you not to get it. Plenty of folks just need a machine for scrolling a social media feed, documents, and Youtube.
But anyone who wants more than what amounts to a Chromebook can get it pretty affordably with the low-end macbooks. Effectively tripling your speed for another $200 is definitely worth it for lots of folks, and memory paging is a lot faster than it used to be.
Benchmarks can be hit or miss, but aren't totally useless:

And finally, the A19 they're talking about using: https://www.cpubenchmark.net/cpu.php?cpu=Apple+A19+Pro
