'''EPYC Embedded 3351''' is a {{arch|64}} [[dodeca-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 1.9 GHz with a TDP of 80 W and a {{amd|precision boost|turbo frequency}} of up to 3 GHz. The 3351 supports up to 1 TiB of quad-channel DDR4-2666 ECC memory.
