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

Context After

② Atomic Claim

從紙面規格看，新推出的 Blackwell Ultra 與 Blackwell 有相同 FP8 效能。
