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.

[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 3451 integrates four 8-port, 16-lane PCIe Gen 1/2/3 (8 GT/s) controllers. All lanes are configurable as x16/x8/x4/x2/x1 wide (e.g. 1x4 + 4x1 + 1x8) PCIe links, some lanes alternatively as SATA Gen 1/2/3 (6 Gb/s) or 10 Gbit/s Ethernet ports. Up to sixteen SATA ports and eight GbE ports are available on this model, as well as four USB 3.1 Gen 1 (5 Gb/s) ports, and the following low speed interfaces: eMMC, UART, LPC, SPI/eSPI, I²C, SMBus, GPIO.
