Evidence

All current evidence in the supply chain points to NVSwitch 7 being the same bandwidth as NVSwitch 6

Context After

Rubin Ultra NVL576

To push the scale up world size beyond 144 GPUs and across multiple racks, optics are needed as we are approaching the maximum compute density that is within the reach of copper. Rubin Ultra NVL576 is now on the roadmap with 8 racks of lower density Oberon.

② Atomic Claim

目前所有供應鏈證據都指向 NVSwitch 7 的頻寬與 NVSwitch 6 相同。

• Epistemic Mode: INFERRED
• Mapping Status: PARTIAL

③ Semantic Frame

{
  "comparison_expression": "目前所有供應鏈證據都指向 NVSwitch 7 的頻寬與 NVSwitch 6 相同。",
  "entities": [
    {
      "id": "04_knowledge_base/NVSwitch",
      "label": "NVSwitch"
    }
  ],
  "frame_type": "COMPARISON",
  "metric": "BANDWIDTH",
  "operator": "EQUAL_TO",
  "qualifiers": {
    "condition_text": null,
    "numeric_mentions": [
      "7",
      "6"
    ],
    "temporal_mentions": []
  }
}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
comparison_entity_0	NVSwitch	NVSwitch

⑤ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
• 最後選擇 review_action
