Ask HN: Performance of Apple Sillicon vs. ThinkPads (Or Other Linux Laptops)

How's the performance, in terms of pure speed (CPU, memory bandwidth) when comparing macOS running in the latest Apple Silicon series vs. running Linux on a comparable (if there's such a thing) laptop like a Carbon X1 or similar?

Would I see significant performance improvements (e.g. compilation speeds) by moving to M3/M4?

Let's say that I do not care about energy efficiency/battery life.
