The Wretched State of GPU Transcoding

"This story began as an investigation into why Cyberlink's Media Espresso software produced video files of wildly varying quality and size depending on which GPU was used for the task. It then expanded into a comparison of several alternate solutions. Our goal was to find a program that would encode at a reasonably high quality level (~1GB per hour was the target) and require a minimal level of expertise from the user. The conclusion, after weeks of work and going blind staring at enlarged images, is that the state of 'consumer' GPU transcoding is still a long, long way from prime time use. In short, it's simply not worth using the GPU to accelerate your video transcodes; it's much better to simply use Handbrake, which uses your CPU."
