The GPU Compute Performance From The NVIDIA GeForce GTX 680 To TITAN RTX

With Darktable the TITAN RTX is basically in line with the RTX 2080 Ti due to diminishing returns for scaling even with these already very large resolution RAW images used for testing that aim to be representative of current RAW image handling. But it is interesting for showing just how the OpenCL Darktable performance compares from the once very capable GTX 680 through now with the ultra high-end TITAN RTX.

OctaneBench 4.0 was recently released and does handle the Turing GPUs quite well. The TITAN RTX here was 6% faster than the RTX 2080 Ti -- though not quite as large of a margin as showing in many of the TensorFlow tests that were ~12% faster.

While running OctaneBench, the TITAN RTX had a 315 Watt average AC system power draw on this 9900K system with a peak of 350 Watts, compared to 299 Watts on the RTX 2080 Ti for an average and peak of 330 Watts.

But even with the slightly higher power draw of the TITAN RTX, the performance-per-Watt was still comparable to the leading RTX 2080 Ti.

The Parboil scientific tests with OpenCL do very well on the RTX 2080 series.
