The memory bandwidth of the M1 Max is 400 GB/s with 64GB of RAM, where as the memory bandwidth of Corsair's 6400MHz DDR5 32GB RAM module is 51GB/s per stick, or 102GB/s for the M1 Max equivalent.
- rowanG077 5y ago51GB/s * 8 (octa-channel, not dual channel as you are calculating) is 408 GB/s. Basically the same as the M1 Max. It's not fair to use an off the shelf product since even if the RAM is slotted Apple wouldn't use an off the shelf product. Whether they use slotted RAM or not has nothing to do with performance. It's a design choice. For the mobile processors it makes total sense to save space. But for the Mac pro they might as well use slotted RAM. Unless they go for HBM which does offer superior performance.
