I have a Hackintosh with a GTX 570, and 12 core setup with 24 gigs of ram.
When I have "Use GPU for Red Debayer" the HDRx controls do nothing, and when I do the 2 source nodes on the color correction, they are the same. If I unchecked the setting, restarting Resolve, the 2nd source is the darker exposure. This is the same in CUDA and OpenCL mode.
In DCI 4K Flat timeline with 1 node that had level adjustments and High soft clip on a non HDR red file, I am getting 20 FPS using CUDA, 12 using openCL with the GPU Red debayer (And having it downscaled to 1080 for display) and having it debay at full res.
Without the GPU for Red, I am getting 15 fps with CUDA, and 14 FPS on openCL
So, in OpenCL on my Graphics card, the GPU Red debayer actually slows down the preformance, and in CUDA I am getting a 25% speed boost.
