I did a terrible, loose, undocumented, once-off 4k 10 bit test and thought it was near realtime in encoding fps, depending. Haven't tried x265, however suspect 4k won't be anywhere near gpu speed.
x265 can itself use the intel svt libraries for rapid acceleration. But I doubt you'll get realtime 2160p in software on anything less than a monster workstation.

GPU is fast, but it has substantial quality/efficiency limitations compared to even a performance tuned software encode.
