Blender 2.81 (bmw27)

Blender is a free 3D graphics software for rendering (creating) 3D bodies, which can also be textured and animated in the software. The Blender benchmark creates predefined scenes and measures the time (s) required for the entire scene. The shorter the time required, the better. We selected bmw27 as the benchmark scene.

V-Ray CPU-Render Benchmark

V-Ray is a 3D rendering software from the manufacturer Chaos for designers and artists. Unlike many other render engines, V-Ray is capable of so-called hybrid rendering, in which the CPU and GPU work together at the same time.

However, the CPU benchmark we used (CPU Render Mode) only uses the system's processor. The working memory used plays a major role in the V-Ray benchmark. For our benchmarks we use the fastest RAM standard approved by the manufacturer (without overclocking).

Due to the high compatibility of V-Ray (including Autodesk 3ds Max, Maya, Cinema 4D, SketchUp, Unreal Engine and Blender), it is a frequently used software. With V-Ray, for example, photorealistic images can be rendered that laypeople cannot distinguish from normal photos.
