OTOY generates more and more positive feedback. With OctaneRender, the company is not only developing one of the most feature-rich and powerful renderers, OctanRender, but also a corresponding benchmark called OctaneBench. We`ve been using OTOY`s benchmark for some time now, most recently with our look at Nvidia`s Quadro RTX 4000. OctaneBench`s results will become more and more interesting with the upcoming OctaneRender 2019, which supports Nvidia RTX.
OctaneRender 2019 launches a new rendering engine called Brigade and with it OTOY is able to take advantage of the latest GPU technologies such as RTX, DXR and Vulcan. The use of Vulcan means that this future Octane version will add support for AMD`s Radeon GPUs.
We spoke with OTOY at the Nvidia GTC this month and learned that using the accelerated features of RTX will be suitable for final frame rendering after OctanRender 2019 ships. Ultimately, this is what we expect from any company that develops a renderer around accelerators like the RT cores. As we understand it, any renderer that promises RTX support should be suitable for final frame rendering. These include V-Ray, Redshift, Arnold GPU, Dimension CC, RenderMan, and Solidworks, to name a few.
Currently, primary version of OctaneBench 4.00 supports current GPUs, but not the special processors on RTX Maps. To test these now, you need a special version of OctaneBench, which you can easily find in the official forums. This benchmark is considered a preview version, but it does a good job of highlighting the kind of accelerations you can expect when using RTX.
To get quick results, we threw every RTX map we have into the workstation rig and let you rip. Here`s a quick look at the test PC used and then the results:
| Workstation Test System | |
|---|---|
| Processor | Intel Core i9-9980XE (18-core; 3.0 Ghz) |
| Motherboard | ASUS ROG STRIX X299-E GAMING |
| Memory | G.SKILL Flare X (F4-3200C14-8GFX) 4x8GB; DDR4-3200 14-14-14 |
| Graphic | NVIDIA GeForce RTX 2080 Ti (11GB; Creator Ready 419.67) NVIDIA GeForce RTX 2080 (8GB; Creator Ready 419.67) NVIDIA GeForce RTX 2070 (8GB; Creator Ready 419.67) NVIDIA GeForce RTX 2060 (6GB; Creator Ready 419.67) NVIDIA Quadro RTX 4000 (8GB; Quadro 419.67) |
| Audio | Onboard |
| Memory | Kingston KC1000 960GB M.2 SSD |
| Power Supply | Corsair 80 Plus Gold AX1200 |
| Housing | Corsair Carbide 600C Inverted Full-Tower |
| Cooler | NZXT Kraken X62 AIO Liquid Cooler |
| Operating System | Windows 10 Pro build 17763 (1809)/td> |
It is important to note that these scores are made up of three different scores that represent the performance for three different kernels: info channels, path tracing and global illumination. Info channels see a 4.5x performance increase with “RTX on”, but it is the least important of all. Path tracing and global illumination make up 90% of the total score, and both see about 2.5x acceleration with RTX on.
Scaling over these five maps is not too interesting just because they scale exactly as we would expect. The bigger the GPU, the better the performance. In the case of the 2080 Ti it is about 33% faster than the 2080, regardless of whether RTX is on or off.
These values result in faster render times for the faster maps. An advantage of 33% may not seem too significant when we talk about a score, but higher scores here mean greatly improved performance – extremely important in a real-time rendering engine like Octane.
OctaneRender 2019 is not quite finished yet and this will certainly not be the only time you will hear from us about this renderer. As soon as the final build of OctaneBench RTX is released, we will test again and see how things have changed. As it looks now, it`s not hard to be impressed by the massive accelerations you`ve seen with RTX. Since this is the final frame rendering, the results are relevant for absolutely every OctaneRender user.
Thank you very much for your visit.
