EPYC Embedded 3301 is a 64-bit 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 Zen microarchitecture, this chip operates at 2 GHz with a TDP of 65 W and a turbo frequency of up to 3 GHz. The 3301 supports up to 1 TiB of quad-channel DDR4-2666 ECC memory.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

Cache

Main article: Zen § Cache

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes.
