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 memory.
- Main article: Zen § Cache
[Edit/Modify Cache Info]
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.

The EPYC Embedded 3301 has 64 PCIe lanes that are MUX'ed with a number of other ports and can be reconfigured as either SATA ports (up to 16 such ports), or as GbE ports (up to 10 such ports), or any mixed configuration of those options.
