Obviously, there are a lot of open-source applications that can be run on Apple computers.
However I have never seen published benchmarks for them.
A benchmark that would be valid for comparing the efficiency of an Apple computer with a non-Apple computer would be to compile using gcc a big software project. A cross-compilation of the project would be more accurate, because for a native compilation target the compiled files might be not the same.
