Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 24 stories with headroom

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 axis applies to this product kind (peer products hold positive or none verdicts on this story), so lack of evidence for an applicable capability is "none", never "na".

    nonemoves PA Scoreimpact 30

    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.

    nonemoves API qualityimpact 30

    This is a hardware accelerator with ROCm software docs but no evidence of an interactive API reference with runnable examples — the OpenAPI probe returned 404s on all candidate paths and no interactive playground/notebook reference is mentioned.

  8. Agenticness — how well agents can access and operate the productDownload a machine-readable API spec (OpenAPI or equivalent)

    nonemoves API qualityimpact 30

    The evidence pack includes a direct probe showing all standard OpenAPI/Swagger endpoints return 404 on AMD's ROCm docs site, and no other citation mentions a machine-readable API spec for MI355X's software stack or management tools.

Showing the top 8 of 24 — every none/partial verdict in the story verdicts table is headroom.
