Description of problem or question:
I just tried out the amd hardware encoder with my rx580. While it was about twice as fast, it was less than half the quality. A 12 minute h.264 1080p video was reduced to 305MB, which was confusing, because the x264 software encoder produced a 190MB file. When I compared the footage, I at least expected the 305MB file to be better. But compared to the software encode, detailed textures were noticeably worse. You could see that the textures were just smushed into a uniform cake. The software encode was much better.
Am I the only one who got this kind of result? Is it AMD or handbrake at fault? And would nvenc provide better quality? It kind of sucks because I have quite a few videos to transcode.
Thank y'all for the help

That's all correct and typical of my experience with hardware QSV encoders. If I run RF 20 on software x264, I find that CQ /RF 13-14 hardware is reasonable quality, but still not quite there.
