Processing speed - Do I need more power?

Roon Software Discussion
1

I have an Intel NUC NUC7i5BNH PC i5-7260U 3.4GHz 16GB acting as my server running on Rock. I’m running a bit of upsampling (only up to 96kHz) and speaker setting. The processing speed is around the 10x mark. Is that ok or should I look to get a more powerful server? Not sure if I should be using a more powerful core as is or if I’d need one if I start using more DSP.
Apologies if this is in the wrong area of the forum. Just looking for the biggest crowd for some guidance.

No, it’s fine … you have ten times the processing performance necessary to perform the task!

Thanks. So basically, as long as the processing speed is 1x or greater, it’s fine and nothing more is required?

Yes, that is correct.

Well that’s really good to know. Based on other posts I’d seen, anything less than 10x was not great. Thanks @mjw !

Interesting to see that there is no processing speed shown if I’m playing a native 96kHz track with speaker settings yet when I’m playing an upsampled track with speaker setting active, processing with is around 10x. Disabling speaker settings and the processing speeds jumps to around 20x

I believe Roon does not show processing speed if it is above 100x or something like that.

Surprised that running any kind of DSP can take up that much processing power. If all I do is enable upsampling 44.1 to 96kHz, it states processing power of about 20x which would suggest it’s knocked at least 80x off processing power just by doing that.

Not quite.
With no upsampling, the processing speed was not shown so it would have been 100 or greater. This means that the stream processing was using 1% or less of the processing capability of one core.

When you set the upsampling, the processing speed decreased to 20x. This means that it was now taking 1/20th or 5% of the processing capability of one core.

Thus the difference in utilised core capacity is about 4% of the total core capacity.

As a consequence,although the amount of processing has increased by a factor of 5, the amount is still low.

Thanks @Wade_Oram That’s a very helpful explanation.
