Google unveils TPU 8tx for secure computing and TPU 8i Max for inference

Two new eighth-generation chip variants target secure training for regulated industries and long-context inference Google has introduced two new members of its eighth-generation Tensor Processing Unit family: the TPU 8tx, built for large-scale training, and the TPU 8i Max, aimed at low-latency inference. The chips were unveiled on November 9, 2026. They signal that Google’s custom silicon strategy is getting more specific, not more general. Investors seemed to like the direction. Alphabet shares rose more than 2% in premarket trading after the announcement. What Google actually announced Neither chip is a clean-sheet design. Both are reconfigurations of processors Google had already put on the table: the training-focused TPU 8t and the inference-optimized TPU 8i. The TPU 8tx is the variant with a security badge. It is designed for confidential computing workloads, with government agencies and regulated industries as its target customers. To get there, Google worked with AMD on hardware-level encryption. Data protection is handled at the chip level itself, rather than relying solely on software layers stacked on top. The TPU 8i Max goes after a different problem. It is tuned for AI ...
