Does this come with a cooler? If so is it any good?

This does NOT come with a cooler, as most people getting this CPU would opt for a better cooling solution anyway since this does require more cooling than the mid-tier R5 or R7s

Difference between X and XT?

100 GHz difference. Basically a little bit faster than the X.
