EPYC Embedded is a family of 64-bit multi-core x86 embedded microprocessors designed and introduced by AMD. Those processors are primarily aimed at networking, storage, and edge computing devices. EPYC Embedded effectively succeeded the Opteron A1100 series of embedded microprocessors (although those were actually based on ARM, not x86).

Overview

The EPYC Embedded family is a low-power variant of the EPYC line that primarily marketed towards embedded devices such as networking, storage, and edge computing devices. Those parts have lower TDPs and come in a much smaller package allowing for denser integration.

Members

3000 Series (Zen)

See also: Snowy Owl and Zen µarch

Introduced in early 2018, the 300 embedded series is based on the Zen microarchitecture using the same dies as the server EPYC processors. 3000-series come in anywhere from 4 to 16 cores as well as with and without SMT support. Models with 8 or less cores come in a single-die configuration and uses a single-chip module Package SP4r4 while models with more than eight cores come in a dual-die configuration and use a multi-chip module Package SP4. Both packages are ball grid arrays (BGAs) and are pin-compatible with each other. Geared toward embedded applications means those parts have lower TDP than their server counterparts. Depending on the die configuration, the features of the dual-die config are mostly double that of the single-die config.

• Dual-die Models
  • Mem: Quad-channel 64-bit DDR4-2666 w/ ECC, up to 1 TiB
  • I/O: x64 PCIe lanes MUX'ed with SATA/GbE and can be mixed configured PCIe and up to 16 SATA ports and up to 10 x 10GbE ports
  • TDP: 65-100 W
• Single-die Models
  • Mem: Dual-channel 64-bit DDR4-2666/2133 w/ ECC, up to 512 GiB
  • I/O: x32 PCIe lanes MUX'ed with SATA/GbE and can be mixed configured PCIe and up to 8 SATA ports and up to 4 x 10GbE ports
  • TDP: 35-50 W

The ISA and Technology applies to all models.

• ISA: 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
• Tech: Precision Boost, 2-way SMT, AMD-Vi, AMD-V, Secure Memory Encryption (SME), and Secure Encrypted Virtualization (SEV)
