The cited article is pretty clear: the M1 Max maxes out at (approximately) 100 Gb/sec per a single CPU core, 243 Gb/sec per a CPU cluster, and 409 Gb/sec per the entire SOC.

They did not (or, rather, could not) measure the theoretical peak GPU core saturation for the M1 Max SOC because such benchmarks did not exist at the time due to the sheer novelty of such wide hardware.

So, which part of "We are talking about the memory bandwidth available to the CPU cores and not all the co-processors/accelerators present in the SoC" you didn't understand?
