I saved a simple project here:
You can download it and test export to 44.1/16bit wav if you like - it’s built with only basic effects so it SHOULD load in LE/Artists versions as well as 9.5 Pro. Only about 200 megs, so it won’t take but 5 minutes to test it on your rig.
That way we could get some proper real-life test going to see what kind of CPU core count and type is the fastest in basic audio exports in Cubase.
Here’s a list of some results gathered - so far to my surprise Ryzen leads by a good margin:
81.8 sec i7-6700K @3.2Ghz
43 sec - i7 3770K (4096 samples)
35.2 sec i5-7600K 3.80 GHz Buffer 2048
32 sec – i7-3770K @4.5GHz (2048 buffer)
29.72s sec - Dual Xeon (E5645) 2,4 GHz (12c), Mac Pro 5.1
28.7 sec i7-6700K @4.6GHz
27.3 sec – i7-2600 @3.4Ghz
25 sec – Mac Pro Touchbar 2017
23.6 sec 2,7 GHz Intel Core i5 8 Gt 1867 MHz DDR3, Macbook Pro 2015
23 sec – i7-6700K @4.6Ghz
13.19 sec – Ryzen 7-1700 @3.0Ghz
9.98 sec i7-7700K @4.2Ghz (4c)
8.3 sec i7-8700K @5GHz (6c)
8.12 sec i7-6840X @4.2Ghz (6c)
If you do export it, time it with a stopwatch from the moment you hit export to the moment it hits 100% (rather that than finished screen) because it’s easy to be accurate at 100% since you can follow the percentage grow.
My i7-6700K @ 4.6GHz did it in 31.8 seconds at first try.
I also tried it at native 4.0GHz and got 32.5 sec, so it’s interesting already in that 15% increase in base clock only gave 2% increase in exporting speed.
I also ran it without Hyperthreading, and exactly same time was spent. Later I changed to 32 bit audioengine and killed all other processes and the best I got was 23 seconds.
I would guess in a larger/heavier project a higher clock would yield a better increase in overall time used, but still interesting.
I’d LOVE to hear how fast can, say an older 16 core or so Xeon crunch it, and also newer ones like Ryzen or Threadripper builds.
