'''EPYC Embedded 3101''' is a {{arch|64}} [[octa-core]] [[x86]] embedded microprocessor introduced by [[AMD]] in early [[2018]] for dense servers and edge devices. Fabricated on a [[14 nm process]] based on the {{amd|Zen|Zen microarchitecture|l=arch}}, this chip operates at 2.1 GHz with a TDP of 35 W and a {{amd|precision boost|turbo frequency}} of up to 2.9 GHz. The 3101 supports up to 512 GiB of dual-channel DDR4-2666 memory.
