As much as I tried to compare measurements to @simon_pepper’s post above, I couldn’t get a good head to head comparison for various reasons. So here are some cases where performance was tested on a NUC8i7 running ROCK:
(All comparisons done with 24/88 Daft Punk Random Access Memories)
Convolution Filter running on one Zone 60X
Convolution Filter running on two Zones 54X
Convolution Filter running on three Zones 43X
(This was a real surprise to me. I haven’t done this before but I found it odd that running convolution filter DSP on three zones ran almost as fast as 1 zone. I guess that is a benefit of a quad core processor on the i7?)
Playing DSD64 file (Santana Abraxas), no convolution > 100
Playing DSD64 file with convolution to one zone 3X
Upsampling to DSD with no Convolution DSP
Convolution Filter, upsampling to DSD256 1.9X
For the record, I don’t prefer DSD upsampling. I like the way my DAC does things itself.
It would be very helpful for this thread if someone could post conditions that either an i3 or i7 processor choked on.
