This whole thread needs a huge amount of salt and some empirical examples. I think if you compared side-by-side it’d be different. I remember my upgrade from 2019 MacBook to M1, when every single task felt about 50% faster. Or from swapping a window laptop’s HDD with an SSD. (Absolutely massive performance improvement!) Waiting forever for older windows computers to boot, update, index or search files, install software, launch programs, etc. Waiting ages for an older iMac to render an iMovie timeline.
Others in the thread talking about the heyday of older spreadsheet and document programs that were just as fast. So? I bet you could write a book on the new features and more advanced tools that MS Excel offers today compared to 1995.
We went from things taking minutes to taking seconds. So you could improve things by 50% and that could be VERY noticeable. (1min to 30s, for example.) If your app already launches in 500ms, 250ms is not going to make your laptop feel 2x faster even if it is. On top of that, since speed has been good enough for general computing for several years now, new laptops focus more on energy efficiency. I bet that new laptop has meaningfully better battery and thermal performance!
