The still life scene was originally set up in Blender 2.79 with photogrammetry models by Oliver Harries:
Special thanks to Oliver Harries for these fantastic free and very detailed models.
All models will use a color, roughness and normal map. All maps were scaled down from 8K to 2K for this test.
Lighting with one High Dynamic Range image.
The Kiwi’s fur has been converted into meshes for this test and used for both scenes.
Both scenes will use Physically Based Rendering by aiStandard (Arnold) and Principled (Cycles) and 64 samples for Camera (AA) and all other passes (Branched Path Tracing in Blender).
The video shows the different render times in real time.

Render time might be affected by recoding with OBS Studio.
In this example ARNOLD and CYCLES are very equal in CPU render time and quality. CYCLES is up to 20% faster. ARNOLD has less noise especially in the darker parts. The Principled shader in CYCLES is using Multiscatter GGX what will result some areas with brighter highlights. ARNOLD just supports GGX. Some parts like the wooden bowl will be lighter. Beside those differences the quality is very similar.
