> A nearly 30 percent increase in unified memory bandwidth to 153GB/s

I'll believe the benchmarks, not marketing claims, but an observation and a question.

1. AMD EPYC 4585PX has ~89GB/s, with pretty good latency, as long you use 2xdimm

2. How does this compare to the memory bandwidth and latency of M1,M2,M3,M4 in reality with all of the caveats? It seems like M1 was a monumental leap forward, then everything else was a retraction.



Why retraction?
