Dual NVIDIA Titan RTX NVLink Rendering Related Benchmarks
Next, we wanted to get a sense of the rendering performance of using two NVIDIA Titan RTX GPUs with NVLink.
Arion Benchmark is a standalone render benchmark based on the commercially available Arion render software from RandomControl. The benchmark is GPU-accelerated using NVIDIA CUDA. However, it’s unique in that it can run on both NVIDIA GPUs and CPUs.
Download the Arion Benchmark from here. First-time users will have to register to download the benchmark.
As we will see in this section using dual NVIDIA Titan RTX GPUs with NVLink has a massive impact on rendering applications that we tested. Arion results effectively double, showing excellent scaling.
MAXON Cinema4D 3D
ProRender is an OpenCL based GPU renderer which is available in MAXON’s Cinema4D 3D animation software. A fully functional 42-day trial version is available for downloaded from the MAXON website here. Note: Even after expiration, the trial can still be used to measure render times.
In Cinema4D R20, the dual NVIDIA Titan RTX GPUs with NVLink cut our render times in half over the single GPU configuration. This shows excellent scaling.
OctaneRender from Otoy is an unbiased GPU renderer using the CUDA API. The latest release, OctaneRender 4, introduces support for out of core geometry. Octane is available as a standalone rendering application, and a demo version is available for downloaded from the OTOY website here.
If you want to go fast here, the dual NVIDIA Titan RTX GPUs with NVLink setup simply blows away the other configurations we have tested with OctaneRender.
Redshift is GPU-accelerated renderer with production-quality. A demo version of this benchmark can be found here.
Performance of the dual NVIDIA Titan RTX with NVLink setup is at the top of our results. Redshift is a very demanding benchmark, and these GPUs scale very well. We did not quite see half the rendering time of the single Titan RTX solution, but the dual configuration is not far off.
On our rendering benchmarks, one thing is clear: if you work against deadlines and need faster render times to get your job done and iterate faster, the dual NVIDIA Titan RTX setup performs extremely well in this domain.
Next, we will have 3DMark results before moving onto power consumption, thermals, and our final thoughts.
