Evidence

Compared to the GB200, FLOPs and memory bandwidth only have a slight shortfall, with capacity being the same with 8-Hi HBM3E, which is of course a significant shortfall to GB300 which has 288GB of 12-Hi HBM3E.

Context After

② Atomic Claim

TPUv7 相較 GB200 只有小幅 FLOPs / memory-bandwidth 劣勢，8-Hi HBM3E capacity 相同；但明顯落後 GB300 的 288GB 12-Hi HBM3E。

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
comparison_entity_0	TPUv7	TPUv7
comparison_entity_1	GB200	GB200

comparison_entity_3	HBM3E	HBM3E

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
