Hello guys, finally got to make a direct comparison of CPU vs CUDA vs RTX on regular stuff I work with. Rhino 6 and V-Ray Next 4.3.
CPU (8700K, 11 threads) - 43:15
CUDA (RTX 2070) - 4:24 (10x faster!)
RTX ON (RTX 2070) - 2:55 (14,5x faster!!!)
Sorry for the massive denoiser. Render times were probably influenced because I was photoshopping the whole time. There was a tiny visual difference between CPU and GPU render.
