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[edit]

Lisa Su introducing EPYC.

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 was launched in June 2017.

Members[edit]

7000 Series[edit]

See also: Naples and Zen µarch

Introduced in June of 2017, first generation EPYC processors are based on the Zen architecture fabricated on GlobalFoundries' 14 nm process. EPYC 7000 series effectively succeeds the previous Opteron 6000 series. All models consist of four Zeppelin dies, providing support for up to octa-channel DDR4 ECC memory of up to 2400-2666 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 non-P models also support two-way multiprocessing utilizing 64 PCIe lanes for this purpose from each CPU.

Additionally, all models support AMD's new Secure Memory Encryption (SME), its subset TSME, and Secure Encrypted Virtualization (SEV) security technologies.

It should be noted that for some models, there are two TDP values given because the TDP will depend on the memory rate used for the system (i.e., either 2666 MT/s or 2400 MT/s). The All Boost frequency is the precision boost frequency that can be applied to all cores when they're all active. When less than 12 cores are active, however, the Max Boost frequency can be applied for even higher performance - provided there's sufficient thermal and electrical headroom.
