Intel® Processors Supporting Intel® SGX

Intel® Xeon® Processors

Intel® Xeon® processors feature built-in accelerators and advanced security technologies for the most in-demand workload requirements — all while offering the greatest cloud choice and application portability. More information about the general features of these products can be found here.

Multi-socket systems containing CPUs of this family support up to 1TB of Enclave Page Cache (EPC), 512MB per CPU; see table below for the EPC size of individual CPUs. These processors support Intel® Software Guard Extensions Data Center Attestation Primitives (Intel® SGX DCAP) with Elliptic Curve Digital Signature Algorithm (ECDSA) based attestation.

This processor family is ideally suited for high performance workloads protected by Intel SGX.

Intel® Xeon® CPU Max Series

Maximize bandwidth with the Intel® Xeon® CPU Max Series, the only x86-based processor with high-bandwidth memory (HBM). Architected to supercharge the Intel® Xeon® platform with HBM, Intel® Max Series CPUs deliver up to 4.8x better performance compared to competition on real-world workloads, such as modeling, artificial intelligence, deep learning, high performance computing (HPC) and data analytics. More information about the general features of this processor family can be found here.

Multi-socket systems containing CPUs of this family support up to 1TB of Enclave Page Cache (EPC), 512MB per CPU; see table below for the EPC size of individual CPUs. These processors also support Intel SGX DCAP with ECDSA-based attestation. Note: The SGX EPC cannot reside in HBM memory, only in standard DDR memory.

Intel® Xeon® D Processors

This processor family delivers workload optimized performance in space and power constrained environments, from the data center to the intelligent edge. These innovative, system-on-chip processors support high-density, single-socket network, storage, and cloud edge computing solutions with a range of integrated security, network, and acceleration capabilities. More information about general features of the processor family can be found here.

Intel® Xeon® D-1700, D-1800, D-2700 and D-2800 processors support up to 64GB of Enclave Page Cache (EPC). These processors also support Intel SGX DCAP with ECDSA- based attestation.

This processor family is ideally suited for Intel SGX-protected IoT workloads.

Intel® Xeon® E Processors

This processor family deliver essential, business-ready performance, expandability, and reliability for entry server solutions. More information about general features of the processor family can be found here.

The maximum supported size of the Enclave Page Cache (EPC) varies on these CPUs, but peaks at 512MB (0.5GB). The table below provides details for the individual CPUs. These processors support Intel® Enhanced Privacy ID (EPID) Security Technology and Intel SGX DCAP with ECDSA-based attestation.

This processor family is ideally suited for smaller Intel SGX workloads, and workloads requiring Intel EPID-based attestation. Note that Intel EPID-based attestation will be deprecated once these CPUs reach End of Servicing Updates (ESU).
