I got an i5 and playing back HD content via Quick-Sync is a
joke. My guess is that it's somewhere around 0.5 - 1W.

I also got a mobile phone capable of display 1080p via HDMI
cable; should be around 0.5W too. Again – due to dedicated
hardware. SD video has to be up-scaled and interpolated. In
the end the difference is probably small.

I don't, but doing it (Soft-Decoding) via CPU consumes at
least 10x more. If I activate Soft-Decoding on my mobile
phone I can kiss goodbye to the batteries... ;-)
