I work on a medium sized project. A full rebuild is about 25 minutes on the M1 Mac and was about 55 minutes on the i7 Mac mini we used before. The "normal" build (what most developers have to face semi-regularly) is about 15 minutes on the Intel and about 4 on the M1. (I checked our CI numbers and can't explain the discrepancy sorry but I would guess the M1 Mac is quicker linking and the link time dominates). Our CI does clean builds once a week, and the other builds somewhat regularly. Reducing the feedback loop by 10 minutes for a developers post merge check is a huge win IMO.
