EPYC Embedded 3101 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 2.1 GHz with a TDP of 35 W and a turbo frequency of up to 2.9 GHz. The 3101 supports up to 512 GiB of dual-channel DDR4-2666 memory.

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.

Expansions

The EPYC Embedded 3101 supports up to 32 PCIe Gen 3 (8 GT/s) lanes. Some of these lanes can be configured as SATA 3 (6 Gb/s) and 10 Gigabit Ethernet ports. Up to 8 SATA ports and four 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, eSPI, GPIO, I2C, LPC, SMBus, SPI, UART.
