Google Unveils TPU 8i Max and TPU 8tx: A Dual-Chip TPU and a Confidential TPU

Google announced two new eighth-generation TPU system configurations: TPU 8i Max, which packages two TPU 8i chips into one package to double compute, SRAM and HBM bandwidth for long-context workloads, and TPU 8tx, which pairs TPU 8t silicon with 5th Gen AMD EPYC hosts for confidential inference with up to 2x lower latency than TPU 8t. Google published no absolute specs, benchmarks, prices or regions for either system, and both are reported to arrive in 2027. The announcement also covered software updates including open-sourced TorchTPU, vLLM and SGLang TPU backends, a TPU agent suite preview, and TPU Sync, which cut median KV transfer latency on Qwen3 235B from several seconds to about 230 ms on Ironwood (TPU v7x).
