My work machine was upgraded from an M1 with 16GB of RAM to an M3 Max with 36GB and the difference in Xcode compile times is beyond belief: I went from something like 1-2 minutes to 15-20 seconds.

Obviously if opening a browser is the most taxing thing your machine is doing the difference will be minimal. But video or music editing, application-compiling and other intensive tasks, then the upgrade is PHENOMENAL.
