I am planning to install a second graphics card in my system and currently i tend more towards AMDs new Radeon 6800. However i know that you would primarily use OpenCL for compute on AMD cards and OpenCL doesn’t have a good reputation(at least on NVidia cards). So i want to ask around whether someone here is using Blender and/or Davinci Resolve on an AMD card and how the performance of the hardware acceleration is. My system will run on a R9 5900X with Manjaro. While i am aware of the fact that with their new cards the performance will be different i want a reference perspective to have an idea of what to expect
For Blender, you can look at https://opendata.blender.org where you can look at results of lots of different GPUs and CPUs running Blender’s benchmark tool. You can grab the tool to add your own data, too.
