v-ray is the Chaos group rendering engine with public benchmark. To install one needs to download from Chaos Group web page. Unfortunately the version used by Phoronix 5.02.00 had a minor bugfix 5.02.01 which changed the checksums. I hacked the checksum values in my .phoronix-test-suite/test-profiles directory and this let me install and run the test.
Profile shows steady running on all cores.
Topdown profile shows backend stalls (mostly memory) and then frontend stalls (mostly latency) limiting the retirement.
AMD metrics shows a lot of floating point code and some branches resulting in branch missprediction.
