Google 推出两款新 TPU 系统：8tx 与 8i Max
Google 把两颗 TPU 8i 拼成一套系统，算力和内存带宽直接翻倍，专门伺候超长上下文；另一款 8tx 走机密计算路线。做大规模推理或对数据安全敏感的团队，可以拿它和 Nvidia 的方案比比价格。
Google 发布两款基于 Trillium 代际的新 TPU 系统：8tx 面向机密 AI 工作负载，8i Max 面向大上下文窗口场景。
8i Max 将两颗 8i 芯片组合在一起，使算力、SRAM 容量和高带宽内存带宽翻倍，从而支撑更长的上下文处理。8tx 则针对机密计算场景，用于处理对数据安全有要求的 AI 任务。
这两款系统是 Google 向 Nvidia 主导的 AI 芯片市场进一步施压的动作，云客户在自研 ASIC 与 GPU 之间的选择空间继续扩大。
Google is on a run! Google has introduced two new TPU systems: 8tx for confidential AI workloads and 8i Max for large context windows.
The 8i Max combines two 8i chips, doubling compute, SRAM and high-bandwidth memory bandwidth, Google says.
Google is pushing further into Nvidia’s AI chip market with two new TPU systems.
