You could also get one or two Ryzen mini PCs with similar specs for that price. Which might be a good idea, if you want to leave O(N) of them running on your desk, house without spending much on electricity or cooling. (Also, IMHO, the advantages of having an Epyc really only become apparent when you're tossing around multiple 10Gbit NICs, 16+ NVMe disks, etc. and so saturating all the PCIe lanes.)
- semi-extrinsic 2y agoDepends what you're trying to do, of course. But if your goal is to scale solving a single problem across many comouters, you need an interconnect that can keep up with your CPUs and RAM. Which means preferrably > 40 Gbps, and then you need those PCIe lanes. 100 Gbps is getting close to affordable these days; in fact dirt cheap if you're willing to mess with weird stuff like OmniPath.
