According to all benchmarks I've seen the M1 Max doesn't offer significant more memory bandwidth to the CPU cores unless (unless the GPU is busy as well). You have run a microbenchmark all all P and E cores to reach the internal bus limitation at ~240GB/s. The remaining ~160GB/s can only be utilised by the other parts of this monster SoC (GPU, TPU, video decoders/encoders, etc.) and in my 14" machine the GPU is throttled by a power limit (probably required by the available cooling). I would love to see how much performance potential there is in the M1 Max die (better cooling with raised voltage and power limits).
