Yes, look at this benchmark comparing the two: http://cpu.userbenchmark.com/Compare…/m340638vs3937
It’s really no contest! If you can wait, I would highly suggest buying the 8700k as soon as it becomes available.
I’m running on an FX 8350 right now, so I definitely feel your pain, but I’m going to hold out for a bit so I can get the better CPU for the better price.
EDIT: It also seems that even thought the 8700k has two less cores than the Threadripper, it still makes more efficient use of those cores over the Threadripper and the difference is pretty stunning. Compared to my 8350, the difference is outright ridiculous!
