Blackwell vs Blackwell Ultra

Evidence

On paper, the newly released Blackwell Ultra has the same memory bandwidth as Blackwell, the same FP8 performance and only 1.5x higher FP4 performance, but when measuring we actually see up to 1.5x better FP8 performance on the Blackwell Ultra, though we only see 1.1x better performance on FP4
