In a very rough sense, looking at Geekbench, the M2 MacBook Air has 5x the single core performance and 10x the multi core performance. Granted, if your workload is typing things into Vim, using the terminal and reading Hacker News, you might not notice. I suspect if you try to load CNN and its 100 ad trackers, you would most certainly notice.
A little off topic, but also illustrative: I found an old 3tb external NAS from 2011. I thought I would copy my backups onto it just to have some redundancy. I realized that the file 5MB/s transfer was going to take literally 7 days. I decided to hop on Amazon and get a 1000MB/s external SSD that could do the job in an hour. Tech really has changed a lot in the past decade+.
