I don’t think you could even top 150GB/s sustained if you ran memcpy on all ten threads at once. (Though that would be 300 total.)

- cormacrelf 5y agoThis turned out to be correct, look at https://www.anandtech.com/show/17024/apple-m1-max-performance-review/2 https://www.anandtech.com/show/17024/apple-m1-max-performanc... -- the "sustained" measurement is on the right hand side of the graph. It hits 243GB/s bandwidth with 8+2 threads, 224 with just the 8 performance cores.
