I am looking into replacing my home server / NAS, and I considered the atom server chips, but they seem just so expensive for their computing power, and also not very power efficient.
The 8 core C2750 has a passmark of 3800[0], with an abysmal single thread performance of 579, and still has a TDP of 20W, and the mobo+cpu assemblies go for ~400$.
For way less, if you're willing to five up on ECC, you can get an i5-7500T and a pretty good motherboard, bringing your TDP to 35W but having a passmark of 7055, and most importantly, a single thread rating of 1924.
This might not matter much if you're use is exclusively NAS, but I will probably end up running some virtualized or containerized server, or streaming video possibly transcoding on the fly, and I'm afraid the Atom might become a bottleneck.
Is there a solution that is somewhat competitive with the i3/5/7 on price and power, and has ECC? And, ideally, that comes in a Mini-ITX form factor?
[0] Obviously the PassMark score is only a ballpark estimate to get an idea of how fast is a chip, but still.

- lultimouomo 10y agoThanks. It looks there are reasonably priced mini-ITX boards that support Skylake Xeons (a note to this that are considering this: v5 E3 (Skylake) use the same socket as Cores, but need a different chipset). The 80W TDP worries me about though, cooling, noise and money/pollution wise (the extra 45W make around 400kWh/year). Considering the CPU will be idle most of the time, do you have figures about the actual idle consumption of an E3 based machine?

- yuhong 10y agoThere are also lower TDP models like http://ark.intel.com/products/53401/Intel-Xeon-Processor-E3-1220L-3M-Cache-2_20-GHz http://ark.intel.com/products/53401/Intel-Xeon-Processor-E3-...
