Google Cloud launched TPU 8tx, the first cloud TPU system with hardware confidential computing, using 5th Gen AMD EPYC processors as host CPU. Enterprises can run inference, fine-tuning or RL while prompts, model weights and intermediate data stay encrypted and isolated throughout. AMD SEV now extends past the CPU to the accelerator: the system verifies a TPU's identity and security setup before granting access to protected memory. AMD says EPYC is now the host CPU at 10+ hyperscalers and frontier AI labs.
