One thing I've learned from running an M1 processor is how much memory bandwidth actually matters for my use case.

I don't see this listed anywhere. Anyone have any ideas how this compares to something like an M1?

DDR5-5600 would be 69.21GB/s[0] which is slightly more than the base Apple Silicon M1 (66.67GB/s) but well under the M1 Pro.

M2 has 100GB/s of unified memory bandwidth[1].

You should be able to find benchmarks online using 7th gen Ryzen and whatever speed DDR5 you plan to pair it with, to get a ballpark.

I wouldn't expect it to touch M1 though, given M1's integrated design.


Is that in reference to the physical locality, or the bit-width of the interface
