What would move AMD Instinct MI355X’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

The evidence includes only bare marketing multipliers (e.g., 'Up to 2.2X AI performance') and mentions of supported datatypes (MXFP6/MXFP4) without any published absolute TFLOPS/TOPS figures broken out by precision (FP8/FP6/FP4/BF16) or with/without sparsity — exactly the kind of unqualified claim the story asks to avoid.
