Context Before

VR NVL72 CPX (Dual Rack): Rubin CPX deployed in a separate rack alongside the VR NVL72 rack

Evidence

More importantly, it formalizes architectural disaggregation between inference prefill (compute-bound) and decode (bandwidth-bound)

Context After

Rubin CPX was originally architected as a GDDR7-based accelerator optimized for prefill, based on three key considerations:

② Atomic Claim

更重要的是，這正式確立 inference prefill（compute-bound）與 decode（bandwidth-bound）之間的 architectural disaggregation。

• Epistemic Mode: ASSERTED
• Mapping Status: COMPLETE

③ Semantic Frame

{
  "attribute": "BANDWIDTH",
  "context_nodes": [
    {
      "id": "04_knowledge_base/Decode",
      "label": "decode"
    }
  ],
  "entity": {
    "id": "04_knowledge_base/Prefill",
    "label": "prefill"
  },
  "frame_type": "ATTRIBUTE",
  "qualifiers": {
    "condition_text": null,
    "numeric_mentions": [],
    "temporal_mentions": []
  },
  "value": {
    "numeric_mentions": [],
    "value_text": "更重要的是，這正式確立 inference prefill（compute-bound）與 decode（bandwidth-bound）之間的 architectural disaggregation。"
  }
}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	prefill	Prefill
context_0	decode	Decode

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
