EPYC Embedded 3151 is a 64-bit quad-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 2.7 GHz with a TDP of 45 W and a turbo frequency of 2.9 GHz. The 3151 supports up to 512 GiB of dual-channel DDR4-2666 memory.


Cache[edit]

[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.

Expansions[edit]

The EPYC Embedded 2151 has 32 PCIe lanes that are MUX'ed with a number of other ports and can be reconfigured as either SATA ports (up to 8 such ports), or as GbE ports (up to 4 such ports), or any mixed configuration of those options.
