Re: [darktable-user] I think I need a graphics card
AMD RX480 + Fedora user here. I am using the GPU with amdgpu (open) drivers for everything. When I have to use darktable, I use the proprietary amdgpu-pro OpenCL drivers. In order to prepare the environment, you have to download the amdgpu-pro drivers from AMD website Unpack the tar.xz file in a folder let's call it /home/user/unpacked After that, there will be a folder /home/user/unpacked/amdgpu-pro that contains subfolders amdgpu-pro-install repodata RPMS SRPMS go in RPMS and take all RPM files that are in subfolder /home/user/unpacked/amdgpu-pro/x86_64 and put them together someelsewhere, for example /home/user/amd_opencl then unpack them all. You will get /home/user/amd_opencl/etc/ /home/user/amd_opencl/lib/ /home/user/amd_opencl/opt/ /home/user/amd_opencl/usr/ Then to run darktable OPENCL_VENDOR_PATH=/home/user/amd_opencl/etc/OpenCL/vendors/ LD_LIBRARY_PATH=/home/user/amd_opencl/opt/amdgpu-pro/lib64/ darktable darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

Also, if you later buy a discrete GPU, darktable can use both for different tasks. However, the Intel integrated chip is no match to a proper AMD or NVidia card. * AMD or NVIDIA -- esp. in view of constraints 3. and 4 > No idea about the current status of AMD or Fedora. I can only say that the proprietary NVidia drivers have been working flawlessly for me on Ubuntu for several years. * RAM for the card -- 4 Gb enough for the images I take (42 Mpix) > Check the RAM memory used by darktable during an export, that should give you an idea of how much memory it needs. 4GB sounds OK to borderline, if you get a good price on 6GB go for it. > * What performance level in AMD's or NVIDIA's current range should I > consider to have a meaningful acceleration of the GPU?

Your CPU seems to be slightly slower than mine, but your proposed GPUs are much faster than mine. I would say you'll get at least a 5X increase in speed with any current middle range GPU. But, as Michael said, there is a point at which a much better GPU won't give you any advantage. Some of the modules in darktable are CPU-only, and your CPU will eventually be the bottleneck.

[darktable-user] I think I need a graphics card
Following a major camera upgrade to a camera with 42 Mpix I have started to run into response-time issues with DT, originally on 2.6.2 but also on 3.2.1. This is both in light table (scrolling, moving from image to image, exporting) and in darkroom mode. Not unexpected given the modest hardware (i3-8100, 8 Gb RAM). I do have images and OS (Fedora 32) on a fast SSD. I have googled this forum and beyond but am not much wiser on what makes sense, so would appreciate advise on what to consider to buy, given the following constraints: * a new graphics card would be for DT only; no other software needs it or would greatly benefit from it * 200 € max -- translates to NVIDIA GTX1650 Super / GTX1660 or AMD's RX570/580 series cards * convenience over last gram of performance -- my time is too precious to have patience for solutions which break at every minor or major kernel upgrade * Fedora -- not necessarily better than any other distro, but simply what I have been using for the last 9 years * My editing is mostly simple, i.e. demosaic, white balance, exposure, profiled denoise, tone adjustments with the occasional parametric or mask limits on these operators Questions: * Is there any value in attempting to get Intel's NEO OpenCL to work or is the expected improvement too little to be relevant -- Phoronix does report 15-25% performance increase vs Beignet and that would be welcome (and as Intel open source) * AMD or NVIDIA -- esp. in view of constraints 3. and 4 * RAM for the card -- 4 Gb enough for the images I take (42 Mpix) * What performance level in AMD's or NVIDIA's current range should I consider to have a meaningful acceleration of the GPU? For reference: my system currently completes the benchmark pictures of Phoronix in 36/18/15 seconds (Boat, Masskrug, Serverroom). Thanks for your advise!
