It's a dedicated ASIC encoder/decoder.  It easily rapes CUDA.

QuickSync beats CUDA in both speed and quality.

I believe nVidia added an ASIC encoder in its Kepler line (GTX 6xx) but I haven't heard much of it.

There's currently no (consumer grade) hardware which does anything higher than 8-bit YV12.
Note that "CUDA decoding" actually isn't really using CUDA to decode, rather, it uses it as an alternative interface to DXVA.  It has some advantages (probably none that matter to most people), but otherwise, is the same as typical DXVA.
