I was really looking forward to testing the AMD EPYC 3000, and here’s why: the EPYC 7000 series processors, both on the first - generation core (Naples) and the second-generation core (Rome), are a real hit and a breakthrough in the world of cloud computing and virtualization. But not a single cloud lives a person, and for dedicated network gateways, NAS-s, various security systems or for peripheral computing, 32 cores-a clear bust. In such tasks, rarely anyone loads more than 4 cores, and compactness and the ability to work well, literally under the feet of the sysadmin, and not in a room with air conditioning - are qualities for which customers pay money. Intel has a wonderful Xeon D processor for these tasks, on which you can produce just freaky compact, but very powerful motherboards of the Mini-ITX format. There are 16 threads, and 10GBASE-T Ethernet controllers, and Oculink ports for SATA or PCI-E drives, and M. 2 slots: well, just everything you need for Edge Computing.
And if Intel is in a very advantageous situation, could do such a miracle as Xeon D, all AMD need is just to cut off the single crystal from chiplet your EPYC 7000, solder the legs to it - and get EPYC 3251: the same 16 threads, same SoC, only this processor was born in a family where the word “security” is not an empty phrase, but means you are not afraid of the attack on the microcode and medicines from them, slowing down the speed of the host.

|Number of memory Channels||4||2|
|Max. Frequency of DRAM, MHz||2133||2666|

We have a motherboard that reveals the whole essence of an integrated processor with TDP 55 Wt. In the Mini-ITX format, the ASRockrack EPYC3251D4I-2T model has a pair of 10-Gigabit copper interfaces, supports up to 256 GB of RAM, and on conventional RDIMM modules, and not on expensive LRDIMM. If you want to save even more, you can use desktop “non-ECC” memory.
As you can see, in the RAM area, the differences between the EPYC 3251 and the Xeon D-2143 are very significant: AMD has fewer channels, but higher frequency, plus the ability to use desktop RAM.
