'''EPYC Embedded 3151''' is a {{arch|64}} [[quad-core]] [[x86]] embedded microprocessor introduced by [[AMD]] in early [[2018]] for dense servers and edge devices. This processor has CPU cores based on the {{amd|Zen|Zen microarchitecture|l=arch}} and is fabricated on a [[GlobalFoundries]] [[14 nm#GlobalFoundries|14 nm]] process. It operates at 2.7 GHz with a {{abbr|TDP}} of 45 W and a {{amd|precision boost|turbo frequency}} of up to 2.9 GHz. The 3151 supports up to 512 GiB of dual-channel DDR4-2666 memory.

The EPYC Embedded 3151 integrates two 8-port, 16-lane PCIe Gen 1/2/3 (8 GT/s) controllers. All lanes are configurable as x16/x8/x4/x2/x1 wide (e.g. 1x4 + 4x1 + 1x8) PCIe links, some lanes alternatively as SATA Gen 1/2/3 (6 Gb/s) or 10 Gbit/s Ethernet ports. Up to eight SATA ports and four GbE ports are available on this model, as well as four USB 3.1 Gen 1 (5 Gb/s) ports, and the following low speed interfaces: {{abbr|eMMC}}, {{abbr|UART}}, {{abbr|LPC}}, {{abbr|SPI/eSPI}}, {{abbr|I<sup>2</sup>C}}, {{abbr|SMBus}}, {{abbr|GPIO}}.
