A short article covering some of the best computer system configurations for rendering with V-Ray Next GPU.
One of the big advantages of GPU-based rendering is that you can easily put multiple video cards inside a single workstation. How much benefit does each additional card provide for V-Ray Next, though? We put four GeForce RTX 2080 Ti video cards to the test to find out!
V-Ray Next is made up of two rendering engines: a traditional CPU based renderer, as well as a GPU-based hybrid engine that can run on both GPUs and CPUs for extra performance. With the launch of NVIDIA’s new GeForce RTX “SUPER” series of video cards, we are taking a look at how the whole RTX lineup performs on the GPU side of V-Ray Next.
V-Ray is a hybrid rendering engine that can run on both CPUs and GPUs, depending on the version that is used. The current benchmark only measures CPU and GPU performance separately, though, and while that is not ideal or a perfect match for how the modern V-Ray Next engine performs it can still be helpful to look at when comparing GPU rendering performance. Let’s see how NVIDIA’s new GeForce RTX 2070, 2080, and 2080 Ti cards stack up against the previous generation.
We’ve previously tested the new Hybrid Mode in V-Ray RT 3.6, which combines CPUs and GPUs in order to speed up rendering, on Intel’s Skylake X processors. This time around we are going to test on AMD’s Threadripper 1950X, and use even more powerful GPUs than before. We also take a look at GeForce GTX 1080 Ti vs Titan Xp performance.
New in V-Ray RT 3.6, Chaos Group has added Hybrid Rendering: the option to combine CPUs and GPUs in order to render images and animations even faster. We give an overview of how this works, and then explore the impact it can have on rendering speeds.
Benchmark results demonstrating that PCI-Express x8 vs x16 speeds don’t impact GPU rendering performance.
