## AI 摘要

很棒的框图，@GoogleCloudTech。这里有个错误。根据图示，HBM3E 是 12 层而非 8 层。对于 TPU 8t 的 6 个 HBM 堆栈容量，必须是 12 层才能达到所引用的 216GB HBM 容量。

## 正文

Great block diagram， @GoogleCloudTech. There is an error here. The HBM3E is 12-hi not 8-hi as per the diagram. At 6 stacks of HBM capacity for TPU 8t， it must be 12-hi to achieve the 216GB of HBM capacity quoted.
