In the chart above, NVIDIA’s RTX 3090 is twice as fast as the RTX Titan, which was the top consumer video card from the last generation, while costing $1000 less and maintaining the same amount of VRAM. With up to 18X faster rendering than CPU-based solutions and enhanced performance with NVIDIA NVLink™, V-Ray Next GPU with RTX support provides incredible performance improvements for your rendering workloads. Render speed is primarily determined by the number of CUDA cores (the more the better) and the GPU’s clock speed. When the engine is set to V-Ray GPU with RTX enabled, V-Ray GPU uses the RT Cores in NVIDIA RTX GPUs. Users using AMD will not get the embree acceleration because that’s an NVIDIA bonus For example, the new Hybrid Rendering mode (CPU + GPUs) in V-Ray 3.6 only works with CUDA mode, which requires NVIDIA graphics cards. Second, OpenGL mode only exists in some versions for use with AMD graphics cards, but the main focus is on the CUDA mode for NVIDIA cards.First, we have found them to be more reliable overall – especially for consistently heavy tasks like rendering.

However, we typically recommend using NVIDIA-based cards due to two reasons. V-Ray does have the option to utilize OpenCL which means that you can use AMD cards for rendering. Both of them meet the requirements of Top-tier G PUs for Vray and Cinema4D, with a slight advantage of Xeon W-2245. In the table above, we found that Xeon W-2245 has 48 PCle lanes while AMD Ryzen 9 5900X offers 20 PCle lanes. Top-tier GPUs usually need 16x PCIe 3.0 Lanes to run at full performance without bandwidth throttling. Different CPUs support a different number of PCIe-Lanes.


Chaos Group calls this Hybrid Rendering, so if you are using 3.6 or higher the CPU should still be a factor that affects your render process.Īt first glance, this makes sense because the CPU does help speed up some parts of the rendering process, such as scene preparation (load files) but not many 3D artists know this fact. Starting in V-Ray 3.6 the CPU can be used alongside the GPUs to further boost rendering speed.
