Any links for this? Since my experience shows that Ampere encoding blocks still aren't close to x264 / slow preset when it comes to saving bandwith and delivering quality. Even with power savings it was usually more economically efficient to run encodes on a large (12+ core) machine than to deal with limited amount of nvenc slots on GPUs.
