My goal is to have real time encoding of H.265 with 4k, 50fps, 10 bit per component.
(but 8 bit depth for component is also acceptable - depends on many factors)

If you are looking for a GUI you can take a look at StaxRip, it supports H.265 hardware encoding using the command line tools QSVEncC and NVEncC.

H.265 encoding with QSVEncC requires Intel Skylake.

H.265 encoding with NVEncC requires NVIDIA Maxwell but I'm not sure if all Maxwell cards support it, it definitely works with GTX 960.
