Hardware,
We have tested 4 scenes on this hardware using Progressive mode, the results are double checked. The scene are setup carefully to push the GPUs to 100% usage, to ensure accurate results. All tests run for at least one full minute
First Scene, Gold_Interior
Second scene, Cabinet_01
Third scene, Nutcracker
Fourth scene, Forest_001
Note, this scene includes thousands of leaves and grass objects, and has all shading baked to textures, hence showing a big boost for RTX mode. In most cases CUDA mode should be close to RTX mode in performance
Conclusion,
V-Ray GPU shows very good performance scaling on the latest NVidia GPU generations, nearly doubling the performance every generation.
Best,
Muhammed

- Pascal to Turing shows average 1.6X speedup in CUDA
- Turing to Ampere shows average 2.4x speedup in CUDA and 2.53x in RTX
- Ampere to Ada shows average 1.87x speedup in CUDA and 1.86x in RTX
- We tested the same scenes between the RTX 3090 and RTX 4090, there is 2.15x speedup in CUDA and 2.2x speedup in RTX
