Intel tends to cheap out on the connection to the heatsink (see overclocker forums for the complaints). Which actually results in a hotter CPU to dissipate the same watts. AMD spent the extra few $ for a good thermal connection between the silicon and the heat spreader. The new threadripper and Epyc chips are also physically quite large. It's much easier to cool the head spreader with 8 hot spots spread across the chip than a single smaller hot spot. So generally it's easy to get 180 watts out of a threadripper/Epyc chips than the equivalent Intel. In fact some of the highest end chips are not considered feasible to cool on air. It's either water cooling of throttling, like in the new Intel based Frontera (don't confuse that with the AMD based Frontier cluster). Basically keeping a dual socket Xeon 8280 cool without throttling is not practical on air.
