Here's news coverage of the announcement:I've never seen such numbers, but even if so, it was still useless, because they didn't even come close to the 3070's 3D performance, let alone the 3080.
I can't really speak to the 3D performance aspect.
I haven't seen hard data on this, but I'd expect the CPU cores to have double the aggregate bandwidth as they have in the Max.But it would certainly have affected the overall performance if the processor cores had access to all that bandwidth.
