I might agree that the M1 Air being faster than the previous Macbook Air is one reason why users perceive it as faster, though that doesn't really explain it seeming "much faster." You'd also have to argue that Big Sur makes up for some of the difference, and assume comparisons aren't being made between updated Intel Macbook Airs.
I haven't had an opportunity to use an M1-based device, so I really just have to accept that it's surprisingly fast. Of course, just like some "want to use a Mac", I "want to use a gaming PC/laptop" and so I do. And my gaming PC and laptop are both "very fast." I don't know that their speed would surprise people coming from older, Intel-based PCs or laptops, though depending on what they are doing, they might.
But I still don't know what point you're trying to make. I guess you're just saying people read that the M1 machines are fast, and so they think they are. But there also benchmarks that show it performs remarkably well, on par with low-wattage Ryzen laptop CPUs and in some benchmarks / single-core with high-wattage Ryzen desktop CPUs, which are really fast.
The 2015-2017 12" Macbook was an ultra-thin fanless machine that was delightfully portable but was basically unusable for anything more than basic web browsing. It'd burn my thighs just watching Youtube.
The 2021 M1 Air is a slightly chunkier fanless machine that runs circles around Intel laptops with desktop-class processors, at lower cost and up to triple/quadruple the battery life. It's unlike any Intel laptop you'll find on the market today.
Apple deserves plenty of flak for their laptop design decisions (crappy webcam, fat screen bezels, port selection...) but the M1 is probably the biggest improvement to laptop performance in a decade.
In any case, x86/x64 is a terrible ISA and it really needs to go. Sad that it's still around and I'm surprised it can even run as fast as it does.
Second this. I got the cheapest M1 macbook air in december and it really is streets ahead of competetion in terms of performace/ battery life.
