Google 一年内推出四款 TPU 变体，加码与 Nvidia 竞争
原标题：Google ships four TPU variants in one year as it ramps up competition with Nvidia
AI 摘要
Google 在第八代 AI 加速器阵容中新增 TPU 8tx 和 TPU 8i Max 两款系统，前者面向机密计算，可在处理过程中保持数据加密；后者通过单封装双芯片将同一机架内的算力、内存和内存带宽翻倍。两款产品均基于现有芯片，仅改变封装、网络和内存配置，使 Google 一年内首次交付四款 TPU 系统。Google 还开源 TorchTPU 并支持 vLLM、SGLang，以降低开发者使用门槛，目前外部 TPU 客户已近 100 家，意在从内部工具转向面向外部客户的竞争性平台，与 Nvidia 争夺推理市场。
