I was an unbeliever, but we got some M1 Mac Mini's and this is the result. They even beat the dedicated workstation many of our people have set up. I get when people say it won't quite match a new ryzen for compute power, but in all of our tests, the M1 beat out all our workstations.

What workloads do you run? I’ve got a 16GiB M1 mbp and a 2019 maxed intel and when compiling Java/sbt projects the intel is significantly quicker, albeit also much loader and power hungry.

As the sibling comment mentions, if you're running Intel JDK on M1 it will be slow. You can find M1 native JDK builds here: https://www.azul.com/downloads/?version=java-11-lts&os=macos...

Wow, based on the comments here I decided try out the native M1 builds of Azul.

I see a 4.1x speedup in compiling (including tests), excluding dependency resolution:

  Azul Native M1 java JDK11: 
   ./sbt "clean;compile;test:compile"  
     254.86s user 
     11.84s system 
     519% cpu 
     51.375 total
  Azul java JDK11: 
    ./sbt "clean;compile;test:compile"  
     490.04s user 
     59.48s system 
     269% cpu 
     3:23.81 total

That compiler most probably not native to m1 arm processor.

Are you comparing a binary being run under dynamic binary translation with a native binary?

Not really an honest comparison, if that's the case.
