I think basically all of Intel and NVidias current offerings have hardware 265 decode. But AMD GPUs still only do h.264 (which might be a patent thing, or might just be that their target market doesn't really care. I know I don't, my gaming PC is plenty powerful to just software decode H.265 anyway, although the power efficiency gains would be nice) The mobile market I have no idea about. EDIT: I was wrong about AMD - see replies.

  Ah it looks like I was mistaken, they've had h265 encoding and decoding support for a while. Not sure where my brain got this idea from, I even have an AMD gpu atm. https://en.wikipedia.org/wiki/Unified_Video_Decoder https://en.wikipedia.org/wiki/Unified_Video_Decoder https://en.wikipedia.org/wiki/Video_Core_Next https://en.wikipedia.org/wiki/Video_Core_Next
