V-Ray runs on both AMD and Intel processors, so the choice is down to user preference. As a rule of thumb, the faster the hardware, the faster the rendering. Another use case is the hybrid rendering with V-Ray GPU, where both the GPU and CPU components can render at the same time. When using the GPU engine, V-Ray utilizes the graphics cards for rendering, but also partially uses the CPU (for example, when calculating the Light cache GI solution). V-Ray GPU uses NVidia CUDA or RTX device(s) to perform the ray tracing calculations.Īs you could see, V-Ray is developed and optimized to take advantage of the full capabilities of all hardware components: CPU, GPU, RAM, storage, network and motherboard. Since GPUs are specifically designed for massively parallel calculations, they can speed up the rendering process significantly by an order of magnitude. GPU rendering allows V-Ray to perform the ray tracing calculations on the GPU cards installed in the system, rather than the CPU. V-Ray offers two rendering engines including V-Ray and V-Ray GPU.
