The base M5 starts at 10 cores and scales to 18 cores. The performance is similar to high end dekstop consumer CPUs.

If you don't compile large codebases, why do you care then?
I do compile large codebases and I'm speaking from experience with the same codebase on both platforms. Not "LOC/s" benchmarks
