My layman's understanding was that M1 chips had very efficient low-power/idle usage, and better memory + instructions pipelining architecture for jobs composed of diverse (inconsistent) size and "shape". And that's why it blows away consumer workload Intel chips. In a server high load environment, is this still the case? Continuous load, consistent jobs -- is the M1 still that much better or does its advantages decrease?
