8700K is mainstream like Ryzen. ThreadRipper and Intel X299 are high end workstation chips.
So why include ThreadRipper in any of the benchmarks? Some include ThreadRipper. Some include 7900X, some include one or the other. Some include neither.
That's the confusing thing to me.
I think that they tested TR on some tests earlier, so they included test results if available. I guess, for gaming and workstation processors sets of tests are different, but with some intersections.
