GPU features are not magical general speed-ups for every case of use, sometimes they just don't match the requirements.

I could see a 20-25% speedup for high quality encoding using GPU and fixed-function encoder features with the new, deeper Intel encoder/decoder APIs for preanalysis and such. Not because it would natively produce high quality output, but because it could help determine some optimal encoding parameters.
