Malloc Voidstar posted:You can accelerate parts of the encoding process using OpenCL but every pure-GPU video encoder I've seen (that wasn't a dedicated chip) has looked like poo poo. And I'm pretty sure the CPU-only parts still end up being the bottleneck. https://www.youtube.com/watch?v=_6XYaFqq2mg In case you don't want to watch, the takeaway is that a GTX 660 gives Premiere's encoder exactly as much of a boost as a Vega 64. Unless x264's OpenCL branch is offloading significantly more to the GPU (and I very much doubt it does), you're super correct. I'm curious how weak/old a GPU would have to be to give worse results than the current generation if four years old is indistinguishable still, but that's sort of a moot point.
