Evidence

BlueField-4’s design departs significantly from BlueField-3. Instead of doing a bespoke tapeout with compute and networking, NVIDIA simply reuses their large Grace CPU die, co-packaged with a ConnectX-9 die to make an 800G DPU with massive compute capabilities. 128GB of LPDDR5 feeds the Grace CPU at half the bandwidth of regular Grace. That is 4x the memory capacity of BlueField-3. BlueField-4 can also function as a storage controller, with four BF-4 chips in each Context Memory Storage system.

⑥ 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
