tl;dr: Google expanded its 8th-gen TPU lineup with two new systems: TPU 8tx, which adds hardware-level confidential computing (keeping data encrypted even in memory) for regulated enterprises, and TPU 8i Max, which packages two TPU 8i chips together to double compute, SRAM, and HBM bandwidth for million-token context workloads. Alongside the hardware, Google is pushing broader TPU accessibility via open-sourced TorchTPU, native PyTorch/vLLM/SGLang support, an XLA Serving Engine, and tools like TPU Sync and GKE dynamic slicing to reduce latency and improve utilization.
