> +1TB/s bandwidth. For the past 3 generations, the speed has been 800GB/s...

M4 already hit the necessary speed per channel, and M5 is well above it. If they actually release an Ultra that much bandwidth is guaranteed on the full version. Even the smaller version with 25% fewer memory channels will be pretty close.

We already know Max won't get anywhere near 1TB/s since Max is half of an Ultra.
