If you make 4K encoding with X265, you don't saturate memory controler and in this case 1950X will produce really better result than 7900X.

You have the same problem with R7 1800X and i7-6900K. In all test in 1080p, R7 1800X and i7-6900K are on par for x265 encoding but not in x265 fhd benchmark.

You are expecting too much from 2xFMAC128 vs 2xFMAC256.
ThreadRipper was designed to use as many processes as possible.
See benchmarks on youtube. Gaming + streaming to youtube + twitch + encoding something in Adobe Premiere.
REMEMBER! You have to use multiple x265 encoders to fully saturate all cores with very common 1080p resolution. So in practice there is no escape from that.
