Opteron

EPYC (pronounced epic) is a family of 64-bit x86 high-performance server multiprocessors introduced by AMD in 2017 as the successor to the Opteron family.

Overview

The EPYC family was announced during AMD's Financial Analyst Day on May 16, 2017. EPYC replaces the previous Opteron server family with the introduction of the Zen microarchitecture which was introduced in early in 2017 for the mainstream market. EPYC processors support 1-way and 2-way multiprocessing. The first series of processors based on the Naples codename will be launched in the second half of 2017.

Set to be introduced in the second half of 2017, first generation EPYC processors are based on the Zen architecture fabricated on a 14 nm process and incorporate up to 32 cores. All models support octa-channel DDR4 ECC memory of up to 2400 MT/s supporting up to 2 TiB of memory per socket (for up to 4 TiB in 2-way MP). Each processor has 128 PCIe lanes and support two-way multiprocessing utilizing their Infinity Fabric interconnects.

• All models support everything up to AVX2 (i.e., SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2), and SHA
