By cheap you mean made by the world's second largest X86-64 CPU and GPU manufacturer using more advanced process nodes than their competition?

I doubt there is anything wrong with the card or GPU it's probably a simple issue where the driver applies compression to data that shouldn't be compressed with the same algorithm that compresses color data.

Delta color compression is lossless

Good point, I was wondering and just took a shot at what it might be. Possibly a call that results in rounding where there should be none in it's OpenCL that isn't experienced in F@H or other open CL apps? Or is it an actual hardware issue? Hard to believe AMD would let a die now used for pro series cards out with known issues, but that is just my opinion.

Please put a spoiler over your comment, we don't want to lose brain cells reading this by accident, it's just not fair.

rtg should be miles ahead of nvidia, navi is just as inneficient as any amd card. polaris = 980 competitor with similar power characteristics, navi = 1080 (oc) competitor with MORE power draw on a NEWER node
