Some of them don't – but some of them do, and that improved performance can offer a noticeable productivity improvement.
I recently upgraded from a 2015 Macbook pro to a new i9 one, and right now I'm working on a computer vision pipeline for some data – an embarrassingly parallel task. It takes about 15 minutes to run a process which would have previously taken about an hour. This is a direct improvement to my development experience (trust me!)
But there are a bunch of different reasons. Modern stacks can be annoyingly under-optimised; a large Webpack app with live reloading can be irritatingly slow even on recent machines. Fast SSDs are useful for people working with large datasets. Better GPUs can mean better UI performance and more screen space.
In short, remember that just because you don't need the hardware, doesn't mean that others don't! :)
