I'm talking about the weight / quality ratio for Youtube destination, so by also considering upload time which is a problem for many people, therefore lossless formats are irrelevant. No, the GTX1000 series is not the most efficient for the quality / weight ratio since it does not support B-Frames for HEVC. GTX1650 (original) with GPU TU117 4Go GDRR5 GTX 16x0 and RTX cards have almost same performance and quality for encoding, The object of the discussion is not the encoding speed which I consider sufficient with Nvenc. I do not see the point of doing 4:4:4 starting from 4:2:0 which is largely what is more popular on Youtube.

The normal user is not going to do this, he will be content with the complexity of the settings of software like Handbrake. (or watch video on a smaller mobile phone screen XD) there's no such thing to get good quality and concerning file size with a push of button, unless you are going lossless (and buy an enterprise SSD to spped things up ) I think that you are lost in your settings and that you forget the main thing which is not to have fun with tons of parameters but to have an effective generic solution for the majority of users who want to quickly put a video on Youtube and get a good quality.

It is all about finding the best compromise of quality, small file size and fast encoding time. Unfortunately this depends also on your source material and your encoding hardware.

That's why x264 has dozens (x265 has about 200) options to configure.
