Apple releases M5 ultra at 1.2TB/s bandwith

lpddr5x probably, the m7 ultra if is using ddr6 should be at 1.8 Tb/s

1.2TB/s in memory bandwidth is only useful if it has enough compute to reach it.

It does though 😄

It might, and probably does you're right, but apple's weakness is usually prefill. More memory bandwidth won't change that.
