NUC vs. Nucleus

Continuing the discussion from ROCK on NUC vs. on Nucleus:

I just set up a NUC8i7 with 256MB SSD and a 1TB secondary SSD with 8GB of RAM for less than $700. Spec seems the same or better than the Nucleus+ albeit without the fanless case. I haven’t heard a nucleus+ but is there any way one can justify the price difference other than convenience? It took me less than two hours to set up the NUC and I don’t have any technical skills, just followed the instructions on ROON’s website. I have the unit set up away from my listening room so fan noise is not an issue. Playing though a RP3 with Allo DigiOne into my Benchmark DAC 1 HDR it sounds great and is completely reliable. Thank you ROON for offering this as a low cost option.

Nucleus is meant mostly so Joe Blow can walk into his stereo store and walk out with a working Roon appliance that needs little, if any, tweaking.

If your NUC is in another room, then there is no SQ difference between the two.

And if you need Control4 integration

Congratulations on getting your NUC setup and welcome. It sounds like you have the same setup as mine except for the memory. I went with 16GB ram. Just personal choice.

When I was trying to decide on NUC vs Nucleus + I read in a review somewhere that the CPU in the Nucleus + was a dual core I7. I didn’t know there was a dual core I7 and I don’t know if that is true or a misprint. But dual core vs quad core, price and the desire to build my own was the deciding factor for me.

My background is working with really fast mainframe computers and I suffer from the Tim Allen “More Power” mentality.

I paid $1119 for a Nucleus purchased from Roon. The turnkey, silent Nucleus was worth the price difference to me.

Then you may be familiar with netdata.

I highly recommend installing it alongside RoonServer, to get some actual performance data on Roon, rather than relying on hunches as to what you need hardware-wise.

Some things in Roon (e.g. DSP) are strongly dependent on single-core performance. Other things (e.g. database manipulation) are heavily multi-threaded and benefit from multiple cores. What’s the best price/performance mix for you may depend on how you use Roon.

Alas, I don’t think you can install netdata on ROCK.

That was just me making fun of me, my choice of a platform for Roon and the reasons behind the decision. Right or wrong it works for me. I doubt if I’ll ever learn to use all of the Roon Software’s fabulous features or push it or the NUC to is limits. I just love it, excited about it, having fun with it and enjoying the music.

A bit off-topic, but I have certainly done something wrong. My NUC 7i7 is totally silent. It runs cool and quiet. Even with your ear against it, there is no noise.

No not wrong. I would suspect that for a majority of users, NUCs run pretty quiet. There could be some difference in fan noise depending upon NUC generation and that gen’s particular Intel Chip and it’s power use/cooling needs.

Yeah, I’ve never heard fan noise from my i5 NUC Core machine that sits on my desk.

I have been confused by the expressed concern for noise. People talking about putting it a closet etc. Thought of returning mine for a noisier one; do not want to be cheated. Perhaps the noise is not a defect at all but a feature available at extra cost.

On a more serious note, the NUC was a fun build. It is a cool little thing. For us, it went very smoothly.

I haven’t noticed any heat or heard any sound at all from my NUC8I7BEH, but then my hearing is not as good as most folks. I have the NUC in a media closet so any sound would not be noticeable in my listening area. I do go into the closet to rip cd’s with the attached USB cd player and I can hear the player spinning up. If the NUC is making any noise it is covered up by the AV cooling systems.

I know there are folks with exceptional hearing and I guess any sound invading their listening space would be objectionable. Sometimes I wish I could hear that well but most of the time I’m happy with what I have.

Some NUC’s are noisier than others. It is a problem for some people, not others.

Mike, as I understand it roon really uses more single core performance, hence the choice in the nucleus to go with a gutsy dual core rather than several slower cores.

My i3 based server seems very comfortable with roon as it has fairly decent single and dual core performance

Yep, I agree. Beefier single core performance is better with Roon than a bunch of slower cores.

The Nucleus+ has to have at least 4 cores as you can dedicate up to 4 cores to audio analysis in settings.

Would you recommend a Pentium G3440 over a Core i3-7100H?

I could be wrong, but I think those are logical, rather than physical cores. Most i7s have 4 physical cores and 8 logical cores (AKA “hyperthreading”).

Yes they are logical as it lets me assign all four of my logical processors on my i3

Well. I have a 2nd instance of Roon on my 12 core (physical) Mac Pro and I can assign 12 cores to audio analysis. I don’t know why the nucleus+ would be different.

I have 12 audio zones in my house and at times I’ve run all 12 at the same time with convolution running on 2 zones and upscaling running on 4 others. I may be wrong, but I can’t fathom that a 2 core processor could handle this.
