Hardware requirements when I have big library and want to use upsampling
« on: June 25, 2020, 05:50:22 am »
Hi, I haven't found information for my particular case. Can you help me?

I want to use upsampling (now to dsd256, in the future dsd512) and have a big library which is growing.

What are the optimal hardware requirements on this usage? I want to have comfort and sensible reserves for the future.

Let's assume that library will be over 10,000 albums (100,000 tracks)

I'm wondering what processor and how much RAM will be sufficient.

I'm considering to buy a NUC and I plan to have UBUNTU installed, as well JMC 26

Doing any sort of DSD conversion is one of the most CPU resource intensive operations Media Center can do. If you're intending to convert/upsample to DSD512 I'd be look at higher end AMD and Intel CPUs. Maybe something like Ryzen 5 or higher and Intel Core i5 and higher. Personally if I was going to do this, I'd go Ryzen 7 or Intel Core i7 and higher just to make sure there's some "headroom" so to speak.

RAM probably won't matter as much, you can probably get away with 16GB minimum, CPU is more important here for the intended DSD conversions.

Thank you. Do I understand it in proper way and it will be reasonable not to use NUC? And choose regular CPU not mobile?

No, a NUC won't be powerful enough to handle those DSD512 conversions. You'll know because you'll have issues with music skipping while playing back converted media because MC will do the DSD512 conversion on-the-fly but the CPU won't be powerful enough to keep up, so you'll have issues with music skipping while playing. Not too sure about mobile CPUs, but honestly I'd avoid those too because they're typically less powerful than desktop CPUs.

The DSD512 conversion would be even worse with multichannel content.

My Nuc8i3/8gb and Ubuntu 20.04 upsampling to 4xDSD runs cpu between 40/70%.
I think that a Nuc8i5 or a Nuc10i5 should be enough
... my library is over 176.000 files
