> While 243GB/s is massive, and overshadows any other design in the industry, it’s still quite far from the 409GB/s the chip is capable of. More importantly for the M1 Max, it’s only slightly higher than the 204GB/s limit of the M1 Pro, so from a CPU-only workload perspective, it doesn’t appear to make sense to get the Max if one is focused just on CPU bandwidth.
It's shared with the GPU, so limited it to CPU-only doesn't seem very fair. In fact, I think not having to transfer data to the GPU is another big part about why, at least for casual gaming, it packs way more punch than it really has any right to.
