HF 25% slower on 10 core iMac Pro than 6 Core Mac Pro

Unread postby pwnell » 29.12.2017 06:25

I have just received my new iMac Pro 10 Core system. I also have a Mac Pro 2013 with 6 Cores. How is it that rendering a stack of 268 DNG files using method B, and Adobe DNG converter, takes 8min 55sec on the 6 core Mac Pro but 11min 12sec on the 10 Core iMac Pro with its much newer CPU (even though base clock is 500MHz slower)?

Cinebench gets 2045 points on the iMac Pro, and only 950 on the Mac Pro for multi core performance.

That is not even speaking about my Windows machine, 6 Core 6850K CPU overclocked to 4.4GHz that runs the same test in under 3min 39sec. What is going on here? Is Helicon Focus not optimized for 10 cores? It showed 1900% CPU usage most of the time...

We have recently made significant improvements in both per-core processing speed and multi-core optimization. We are now getting good results from a 24-core Intel and 16-core AMD CPUs that we used for testing so the next version of Helicon Focus should work much better. The only problem is that the upcoming updated version of the program is still work in progress. It's already working on Windows with only some UI changes not finished yet, but the Mac version is not functional at the moment so I can't even give you a preliminary build to try right now, unfortunately.

Might I get a copy of the Windows version? I am running Parallels and that would be so awesome!

Sure: https://drive.google.com/open?id=1HN-akaGhlhovfnJ3z0frvrSt6YC6_jFZ
Please note that this version is far from final and has some problems, but should generally be working.
Also note that you will lose some performance to the virtual machine layer, but you should still get a decent boost out of your multi-core CPU.

Thanks, trying it now. What is the difference between the two Method B's? (depth map and legacy)

Depth map is a new experimental method. You can compare it with the old Legacy method.
