H.265/HEVC vs. H.264/AVC: 50% bit rate savings verified

Can H265 benefit from Quick Sync hardware acceleration or is it just for H264?

Skylake has H.265 Quick Sync but previous generations don't.

Quick Sync also isn't exactly what I'd call a high-quality encoder, it is useful for things like realtime streaming or screencast recording, but if you are encoding movies or TV shows you will want a "real" HEVC encoder.

QuickSync works but it's also worth noting that NVIDIA supports it on their second generation Maxwell cards.

All Maxwell cards, actually.

GM107, GM204, and GM200 all use a combination of a GPU shader kernel with some CPU assistance. GM206 (in the GTX 960 and 950) implements a newer revision of the PureVideo decoder that allows H265 to be decoded directly on the video engine.

Let's be careful about decoding vs. encoding.

Has someone compared the results of Quick Sync HEVC encoding with other codecs?

On Skylake and newer, yes.
