AMD boss confirms high-end Navi cards are "on track"

You didn't listen carefully then, on the 5700XT Steve crank the fan to 100% (4600rpm) and the temp was ~70C, stock temp was 88C with 43% fan and this is still winter in Australia where ambient temp is 20C, F1 isn't even an intensive game also. On the normal 5700 Steve cranked the fan to 50% and temp were 68C.
Yes with better cooler you can reduce the temp of the 5700XT but don't expect the any cheap AIB model to improve much over stock. Overall any 5700XT model will be hotter and louder than the comparative 2060 Super model simple because of the higher thermal density of the 5700XT.

You can downclock a 5700 and run cool, and get 2060 Super performance..!

It is about price/performance. Nobody cares about thermals, unless you have a problem. Since AMD cards cost less and perform on par with Nvidia cards costing more, you can easily get a nice cool & quiet GPU.

Nvidia's SUPERs are for people who are stuck on g-sync, otherwise the whole world is moving to RDNA.
