I don't have one, but this suggests it gets about 40 GB/s and can be saturated by a single core. I believe it uses two channels of LPDDR4X-4266, which has a theoretical peak of 68 GB/s.
https://browser.geekbench.com/v3/cpu/8931693 The press release claims up to 400 GB/s on the Max using DDR5. I assume that's calculated based on 8 channels of LPDDR5-6400, which seems like a surprisingly big step and I'm skeptical of what will actually be realized.
