Radeon RX 560 and Resolve?

Hi. I have an AMD Radeon HD6850. This doesn't seem to work with Resolve due to, I think, OpenCL issues. I'm thinking of getting a Radeon RX 560 4GB (amd. com/en/products/graphics/radeon-rx-560 no spaces). While not a huge amount of VRAM, for the type of editing I'll do to begin with, I'm okay with the VRAM aspect. Does anyone have any thoughts on this GPU in terms of use with Resolve? And has anyone, by any chance, used this exact GPU or this series from AMD successfully with Resolve? Thanks.

Hi.

In Resolve the CPU is used to run the app, disk I/O and compression and decompression of codecs.
Resolve does all its image processing in the GPU on the graphics card. More CUDA/OpenCL Cores are better.

I will suggest you start with reading the DaVinci Resolve 15 Configuration Guide:

Here is the RX 580 with 8 GB vRam recommended. When I look at the OpenCL Benchmarks have all of the RX 560's less OpenCL performance than the RX 580. But, may be you can accept it, specially if you only want to use HD resolutions and not 4K/UHD.

For vRam will I say that for 4K/UHD will I recommend at least 6 GB vRam. Better with 8-11 GB vRam. But for HD will you only need 2-4 GB vRam.

And please look in the DaVinci Resolve 15 Configuration Guide for recommendation on CPU, PCIe lanes etc.

Thanks. Yeah, I wouldn't be doing 4K. Do the OpenCL cores also handle Resolve's own interface, in terms of rendering imports, etc.? I mean, my HD6850 does support OpenCL, but when I try import clips, stills and even audio into Resolve, they're just black/blank thumbnails in the media pool, and when I drag them down to the timeline, they don't play. Is this an OpenCL issue? I don't want to fork out cash to buy a mid to high range GPU and then still have this issue.
