Google 发布 TPU 8tx 和 TPU 8i Max 两款新芯片
Google 这次把 TPU 拆成两条线了：8tx 给政府和受监管企业做敏感数据训练，8i Max 专门解决智能体跑百万 token 上下文时的内存问题。做长上下文应用或者在云上选训练卡的话，这两款值得对比一下再下单。
Google 宣布推出两款新 TPU：TPU 8tx 面向大规模训练场景，TPU 8i Max 面向低延迟推理场景，两者定位截然不同。
TPU 8tx 主打安全合规，目标是需要在敏感数据上运行模型和自主智能体的受监管企业与政府客户，训练与数据隔离能力是它的核心卖点。TPU 8i Max 则针对推理阶段的内存瓶颈，专为处理大型代码库、长视频和百万 token 长上下文的智能体负载设计，低延迟是主要优化方向。
这两款芯片显示出 Google 在 TPU 产品线上开始按工作负载细分：一边抢云训练订单，一边押注智能体推理带来的内存需求增长，与 NVIDIA 按场景分层的产品策略类似。
GOOGLE 🔥: New TPU 8tx and TPU 8i Max have been announced!
> TPU 8tx is designed for large-scale training and targets regulated enterprises and governments running models and autonomous agents on sensitive information.
> TPU 8i Max is designed for low-latency inference and addresses the memory demands of agents processing large codebases, lengthy videos, and million-token contexts.
