Stock settings (+/- 3.3Ghz) = 39 seconds, PBO auto (+/- 450W @3.95Ghz = 36 seconds). Manual PBO (500W @3.95- 4.05) also...36 seconds.
It does not scale that well. Because I have overkill cooling (1400W heh, the fans don't even need to spin at full overclock) I believe I can successfully ignore PBO and set the multiplier for x42 and get maybe 33 seconds (I did not set it this way because it's running on Beta bios and I need this PC to be super stable right now) But what is funny is that by this, it has close to 6200 CB15 score, super close to top platinum xeons, but those will reach easily into twenties.
So Corona can't utilize Threadripper as well. Some things to consider is that the benchmark isn't linear, it still have considerable pre-render phase and right now my 2990WX only runs by 30perc. during them, slowing stuff like UHD,etc..
So it's really good, but it's not great. It scales extremely well in some other "benchmarks" I run, namely Marvelous Designer and PTGui 360 stitching. I did not have time to run Vray. We're in super busy work phase, I had to set it up and immidiatelly get it to work for Veronik.
I would still suggest it 100perc. It's much more affordable even compared to OEM/ES 8173M/8180M at their best ebay price, and absolutely superior in single threaded operations which I believe will only improve with the upcoming dynamic mode (automatic process lasso/scheduling in Ryzen master utility). But there is some wasted potential and I can only wonder if it's due to memory (plausible, since 2133 vs 2933 yielded drastic difference) or partly Corona's architecture.
(I believe the dynamic mode would alleviate the issues with Corona's prerender phase as I believe this is where memory bandwidth becomes issue. This set of processes are not multithreading well from start to finish so as long as they will be ofshored to cores with direct memory access, perhaps it can shave some time on benchmark. It will not have any impact on longer rendering time).
