It is generally considered now as good as x264 and x265 at medium preset: https://developer.nvidia.com/blog/turing-h264-video-encoding-speed-and-quality/ https://unrealaussies.com/tech/nvenc-x264-quicksync-qsv-vp9-av1/7/#NVENC-Part-2 (you can find more studies) Turing cards are RTX 20xx and GTX 1650 Super: https://en.wikipedia.org/wiki/Nvidia_NVENC#Sixth_generation,_Turing_TU10x/TU116 If you want to use HEVC to limit size while maximizing quality, Turing NVENC HEVC makes a lot of sense since it is so much faster than x265 or vp9. If you are going to output H.264 I think it is less compelling considering the speed of x264.
