Has anyone here observed such a low performance with Nvidia GPUs with Darktable on Linux? Would you have some recommendations on how to improve it, maybe also how to trick it to allow it to allocate more memory?īelow are the initial parts of the Darktable logs:ĪMD: opencl library 'libOpenCL.so.1' found on your system and loaded 1/4 of their VRAM for OpenCL memory allocations. And, from the benchmarks that can be found here ( GPU benchmarks in darktable), it seems that Nvidia GPUs often allow only approx.

Also, from the log I can see that the Nvidia only allows VRAM allocations only up to 977MB. 30% longer than the older and slower AMD card. However, the results of my tests surprised me - in my experiments, the same set of exports took approx. The OpenCL support worked out of the box. With the Nvidia GPU, I installed the proprietary nvidia-driver-440. I made some basic setup to compare the cards - I selected 30 edited photos and used darktable-cli to export them while logging the debug and profiling info, also watching the GPU resources and measuring the total duration of the whole operation. So I decided to buy that one as well, keep the better performing one and return the other one. Overall, the 1650 Super shall be better performing GPU, although having only 4GB of VRAM instead of 8GB - but from profiling Darktable exports with the AMD GPU, the VRAM consumption was moving between few hundred of MB up to 2.4GB, therefore I thought 4GB VRAM will be ok. Just few days after byuing the AMD card I found Nvidia GTX 1650 Super on sale.

I have used the open source AMD drivers with the necessary OpenCL part installed from the AMDGPU-PRO package. Software-wise, my setup is: Linux Mint 20, Darktable 3.2.1Īt first I bought an AMD RX 570 8GB and got some pretty decent results when compared with processing on CPU only. I decided to build the PC specifically for Darktable and I’m trying to find the best GPU for OpenCL within my budget. Monitor 8 different scenes and easily cue or transition to any of them with merely a single or double click.I would like to kindly ask you for help with issues I’m observing on my new PC build.
