Big encoder test:
TLDW:
NVidia is out in front, AMD is lagging everyone.
AMD lagging in software. Shocking!
I was surprised nVidia was > x264 slow and taking the lead.
Yeah surprised me as well, I remember when using gfx cards encoding was fast, but quality sucked.
At this time the main use case for h.264 based encoders should be real time encoding (e.g. streaming) and backwards compatibility situations. h.265 or HEVC, as tangoseal points out is much better.They all suck. Use CPU h265 its significantly better. Do it when youre goong to sleep and it will be done when you wake up.
Good call I was skimming the early sections and skipped to the end and missed the mixed comparisons of x264 vs NVENC HEVC /NVENC h.265 (and navi encoder) - a non-intuitive comparison. I would think you'd test x265 vs NVENC HEVC for an apples to apples, although that is a long video maybe he explains it somewhere. I personally find these 25+ min videos with tons of graphs and limited time indexes a misfit for the youtube video format. Just post an article so people can skim and focus on the graphs they care about and read the analysis in depth.
Overall interesting results though, the Nvidia hardware encoders are doing well now even with NVENC h.264 compared to x264 slow preset, which is a good quality h.264 encoder but as the name implies.. slow. HEVC has a ~15-50% efficiency benefit over h.264 so you do expect it should do better when compared that way.

Encoding Quality
x264 offers a wide range of presets that change quality significantly, and presets above Faster require CPUs with 6+ cores. NVIDIA NVENC offers consistent quality based on the generation of the encoder. The updated NVIDIA Encoder (NVENC) on Turing-based NVIDIA GeForce GPUs (RTX 20-Series and GTX 1660/Ti) will typically produce superior quality than x264 Fast and on par with x264 medium. While the older generation (Pascal, Kepler) are similar with veryfast/faster quality.
