It ends up being a big optimization target for both Intel and AMD in this regard.įor benchmarking purposes, we fell back to one rendering a frame from a detailed project. With it being open-source, studios can customize it in as many ways as they need to get the results they require. This extends to conferences, use in films and VR, with a dedicated Blender Institute, and everything you might expect from a professional software package (except perhaps a professional grade support package). One of the popular tools for rendering is Blender, with it being a public open source project that anyone in the animation industry can get involved in. Most benchmarks in this case are re-run several times, and the key to this is having an appropriate idle/wait time between benchmarks to allow for temperatures to normalize from the last test. If a system is not properly configured to deal with the thermal requirements of the processor, the rendering benchmarks is where it would show most easily as the frequency drops over a sustained period of time. These tests are some of the most strenuous in our list, due to the highly threaded nature of rendering and ray-tracing, and can draw a lot of power.
All the tests put out some sort of score or time, usually in an obtainable way that makes it fairly easy to extract. As GPU and GPU rendering technology progresses, I expect GPU rendering will become even more widespread and eventually take over as the main production render in most workflows.Rendering tests, compared to others, are often a little more simple to digest and automate. Additionally, Chaos Group’s work on out-of-core geometry for the GPU engine will further reduce VRAM usage, making GPU rendering both more accessible and more efficient for geometrically complex scenes. According to Chaos Group, there is an internal build of V-Ray GPU in the works that offers a speed boost of 47-78% for RTX cards, with more performance gains expected in the coming months of development.* In fact, according to preliminary testing done by Chaos Group, the 2080 Ti with RT core support will more than double the performance of the 1080 Ti. The new NVIDIA Turing RTX graphics cards already save valuable time over the previous Pascal generation, and this is before the new RT cores are utilized by V-Ray (although their Tensor Cores are used in the NVIDIA OptiX AI Denoiser implemented in V-Ray Next). Looking to the future, GPU rendering is extremely promising.
