It's actually not that much slower, at least if you compare machines with the same amount of storage. The M2 and M3 MacBook Air with 256GB comes in at 1700 MB/s[1], while the Neo with 256GB is... drumroll... 1700 MB/s[2].
Yes, Air and Pro machines with more storage are faster. I have not seen any benchmark of the Neo with 512GB, so maybe it lags behind the Air and Pro there. But I've not seen anyone publish a benchmark which actually demonstrates that.
I should clarify that I was referring to the memory bandwidth. Compared to the 100 GB/s of a M3 MacBook Air, the 60 GB/s of the Neo is 40% slower. My M1 Pro MacBook Pro's memory bandwidth is 200 GB/s; that's 3.33x faster than the Neo.
