Description

What CPUs support EPID attestation?

Resolution

All consumer CPUs and all Xeon E-xxxx CPUs that support Intel® SGX support EPID. However, the newest 3rd generation Intel® Xeon® Scalable Processors (codename Ice Lake Server) and all future Scalables only support DCAP (no EPID support).

EPID support was discontinued in newer Scalable Processors primarily because data center customers and the ecosystem have moved towards ECDSA-based attestation, away from EPID, because it afford them more control, relying less on Intel infrastructure.
