Doom9's Forum - View Single Post - Quick Sync, CUDA, OpenCL or only normal CPU? What is the best?

Quicksync is very like CUDA but even more of it is fixed function hardware so it has very low CPU and GPU usage while running. The newest Quick Sync (Haswell) is better quality encoding than older versions. Quick Sync is a bit better quality than OpenCL/CUDA but it is not as good as x264. I don't know what Nero is using for software H.264 encoding.
