Oh, So That's What They've Done
The Xbox Xeriex X as we've noted has an odd memory structure with two different bandwidth numbers.
The reason for this is that it's missing two chips.
It has 16GB of GDDR6 on a 320-bit bus. Logically, that would be ten 2GB 32-bit wide chips in, except that would give them 20GB total.
So instead they have a 10GB bank with five 64-bit wide chips, and a 6GB bank with three more. They share the same bus so the bandwidth is not cumulative.
The 10GB is for graphics and the 6GB is for game code and OS.
