Anandtech site goes into a bit of speculation along with the fie shots.Do you have a link?
Wasn't able to find the specs.
Although I'm curious how you get 400 GB/s with LPDDR5-6400?

For M1 Pro:
The company divulges that they’ve doubled up on the memory bus for the M1 Pro compared to the M1, moving from a 128-bit LPDDR4X interface to a new much wider and faster 256-bit LPDDR5 interface, promising system bandwidth of up to 200GB/s. We don’t know if that figure is exact or rounded, but an LPDDR5-6400 interface of that width would achieve 204.8GB/s.
For the M1 Max:
The packaging for the M1 Max changes slightly in that it’s bigger – the most obvious change is the increase of DRAM chips from 2 to 4, which also corresponds to the increase in memory interface width from 256-bit to 512-bit. Apple is advertising a massive 400GB/s of bandwidth, which if it’s LPDDR5-6400, would possibly be more exact at 409.6GB/s. This kind of bandwidth is unheard of in an SoC, but quite the norm in very high-end GPUs.
