# Confidential Computing

AMD says its 5th Gen EPYC processors provide the host infrastructure for Google Cloud TPU 8tx, the first cloud TPU system to deliver hardware-enforced confidential computing. Previously, Google Cloud's confidential computing portfolio covered CPU-side workloads such as Confidential VMs, Confidential GKE and Confidential Space, not confidential AI acceleration. TPU 8tx uses EPYC's Secure Encrypted Virtualization to extend protection to connected accelerators, keeping prompts, model weights and intermediate data encrypted in CPU memory and in transit, with hardware isolation during accelerator execution, for enterprise inference, fine-tuning and reinforcement learning workloads.

AMD says its 5th Gen EPYC processors provide the host infrastructure for Google Cloud TPU 8tx, the first cloud TPU system to deliver hardware-enforced confidential computing. Previously cloud TPUs lacked that protection; the design extends AMD Secure Encrypted Virtualization from the CPU to connected accelerators, keeping prompts, model weights and intermediate data encrypted in CPU memory and in transit, with hardware isolation during accelerator execution. The capability targets production inference, fine-tuning and reinforcement learning workloads, and AMD says EPYC is the host CPU choice across more than 10 leading hyperscalers and frontier AI labs.
