being inside the cpu package should allow for less than a 1% improvement in latency by my napkin math. its got good latency because it is a top of the line mobile ram setup but that isn’t unique to m1

I 100% agree, but I've audited my code, and on other platforms my code closely agrees with LMbench's lat_mem_rd, which seems pretty well regarded for accuracy.

The latency appears real to me.
