Mitsuba 3 vs V-Ray Benchmark

Mitsuba 3 is a free, open-source, research-oriented system for forward and inverse light-transport simulation. It offers monochrome, RGB, and spectral rendering with optional polarization tracking, and computes derivatives with respect to camera pose, geometry, materials, textures, and volumes. Dr.Jit compiles rendering code for CPUs through LLVM and NVIDIA GPUs through CUDA and OptiX. Python integration supports development of materials, textures, and rendering algorithms, with documentation covering PyTorch interoperability. Installation is recommended through pip and requires Python 3.10 or later. Optional GPU computation requires NVIDIA driver 535 or later; parallel CPU computation optionally requires LLVM 18 or later. The project reports Linux x86_64, macOS aarch64 and x86_64, and Windows x86_64 support. Its plugins cover materials, light sources, and complete rendering algorithms. The Python package includes thirteen variants by default; more require compiling a custom Dr.Jit version with CMake. Tutorials, notebooks, how-to guides, and API and plugin references are provided.

V-Ray Benchmark is a free benchmark for measuring system rendering speed with CPUs, NVIDIA GPUs or both. Its scene tests the RTX and CUDA V-Ray 6 render engines, and the CUDA engine can combine CPU and GPU rendering. Users can run tests that take about a minute or loop them for longer runs, then compare scores with other results. Side-by-side comparison supports up to three configurations, and result details can include core count, clock speed and hyper threading. Users can save, view and share scores, filter results by device and hardware details, and browse or share through the mobile version of benchmark.chaos.com. Result exports are available as a text log or image, and V-Ray 5 Benchmark results remain accessible. The free plan costs nothing and includes the standalone application, CPU and GPU rendering tests, and online result comparison. Listed platforms are Linux, macOS, web and Windows; V-Ray 6 Benchmark supports Apple silicon chips.
