Proceed with caution

Why: The capability is real and shipping in HGX B200, but every quantified performance claim we could verify is either vendor marketing or measured on the prior Hopper generation; the host-side TEE-I/O dependency is not yet GA and even NVIDIA gives no timeline for Blackwell TEE-IO on partner clouds.
Next: Wait for an independent third-party Blackwell CC benchmark (peer-reviewed or analyst) before assuming the 2-5% overhead claim; pilot only via a managed cloud (the GA Azure NVIDIA confidential-GPU path is currently H100+AMD SEV-SNP, not Blackwell+TEE-I/O) rather than self-hosting the full host+GPU TEE-I/O chain.
