谷歌推出 TPU 8i Max 与 8tx 两款第八代系统
谷歌在第八代 TPU 阵容中新增 TPU 8i Max 与 TPU 8tx 两套系统，前者将两颗 TPU 8i 芯片封装为一体，后者以 TPU 8t 搭配第五代 AMD EPYC 主机以保障数据与权重在使用中的安全。谷歌称 8i Max 的算力、SRAM 与 HBM 带宽翻倍，折算约 17.2 TB/s，低于 NVIDIA Rubin 的 22 TB/s；8tx 延迟最高降低 2 倍，但官方未公布绝对规格、价格与基准测试。

▲ Google just added TPU 8i Max and TPU 8tx to its eighth-gen TPU lineup, giving long-context agents and regulated AI their own TPU systems.
The key idea is building new systems around existing silicon, not new chips. TPU 8i Max packs 2 TPU 8i chips into 1 package. TPU 8tx pairs TPU 8t silicon with 5th Gen AMD EPYC hosts to keep data and weights protected while in use.
Google says 8i Max doubles TPU 8i compute, SRAM and HBM bandwidth. That implies about 17.2 TB/s per package, versus 22 TB/s on NVIDIA Rubin. 8tx claims up to 2x lower latency than TPU 8t. It is a trade-off though: Google published no absolute specs, prices or benchmarks for either system......
