EPYC Embedded 3451 is a 64-bit 16-core x86 embedded microprocessor introduced by AMD in early 2018 for dense servers and edge devices. This multi-chip processor has CPU cores based on the Zen microarchitecture and is fabricated on a GlobalFoundries 14 nm process. It operates at 2.15 GHz with a TDP of 100 W and a turbo frequency of up to 3.0 GHz. This model supports a configurable TDP-down of 80 W, and up to 1 TiB of quad-channel DDR4-2666 memory.

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. |
