What GPU benchmarks reflect professional creative workloads beyond gaming?

I'm building a new workstation for 4K video editing and 3D rendering, and I'm trying to decide between several high-end GPUs, but I find most GPU benchmarks online are overwhelmingly focused on gaming performance. While those frame rate tests are useful, they don't give me a clear picture of how these cards will handle sustained compute workloads in applications like DaVinci Resolve or Blender Cycles. For professionals in similar fields, what are the most reliable sources or specific benchmark suites you use to evaluate GPU performance for creative production? How much weight do you put on VRAM capacity versus raw compute power for your workflows, and have you found any significant real-world performance differences between the major architectures that aren't apparent in synthetic benchmarks?
