When the M1 MBPs came out, one of the lead engineers at Twitter said that the improvement in compilation time for their developer’s was so impressive that the saved time would pay for the cost of the machines in less than 6 months in increased productivity. Compilation benefits massively from fast IO, particularly when you’re compiling locally with optimisations off to improve build times, and the disk and memory bandwidth improvement over the Intel machines is huge. Apple claim the new M2 MBPs compile Xcode projects 2.5x faster than the last Intel machines.
