UE4 - intel 7700K or AMD 1800X?

Took me a while but I did a test on mine and friend’s PC.

UE4.15.1 Development Editor

i7 6700k@4.5GHz with 16Gb 2666MHz
21min 5sec

i7 5820k@4.0GHz with 16GB 2666MHz
18min 30sec

both on Samsung m.2 with 2.8GBs reads.

From perspective of a programmer I am bit disappointed with R7. It seems 5820k beats it for same price (and now you can get even faster 6800k) in compilation, even normal i7 gets same time.
But for people with more usage for R7 power like lightmass or other heavy mt it seems like a good choice.
