Thanks guys for sharing.
Seems that there are no big differences between Xeon D variants at idle.
Last weekend one idea come to my mind. Maybe it's a good idea to go with 1518 and if i will miss some processing power go with second one as cluster.
But isn't 1518 too week for my needs as standalone?
I don’t have one yet but if idle power consumption is a concern don’t go for d-2100 series, it’s double the d-1500 series.
Far exceeded by expectations, but it’s also a more performance focused platform, just compact SoC
D-2100 can out perform the silver line of CPU’s, it’s got a high turbo clock as well. E3’s are another vet power efficient option in lower core counts at idle, but uses udimm rather than rdimm which is a kind of turn off.
