My card runs 2038mhz before 60C with an overclock... so you're saying a GTX1080 runs around 2238 at the same settings?
My specific 1080Ti has a maximum power limit of 300w.
Depending on the exact model of the OP's 2070 Super, it's either 215, 240, or 260w...

Some of Msi's 2080s have even higher power limits - 285w max.
Pretty sure I have the hotter card.
The OP's 2070 Super should be capable of similar temps. There's either a case cooling issue, or the gpu cooler's design isn't great... perhaps both.
You can't compare Pascal to Turing, since Pascal is 14nm and Turing 12nm. But the Nvidia max temp spec of the 1080ti is 91C vs 94C on the 1080.
And yes, Good 1080 chips with good cooling can hit +2200Mhz. you can't hit that with 1080Ti. They usually use the same or similar coolers and that extra heat from the larger die size need to be saved somewhere. And a 100 or 200Mhz less clock speed can go pretty far in terms of heat. See details below:
But the 1080Ti is still the faster card, but not necessarily by clock speed. Its a much larger die made up of many more cuda cores than the 1080. More cuda cores mean more speed than less cuda cores. The non-ti versions usually have higher max boost clock speeds than the Ti versions. The higher power limit is needed to power the higher count of cores. But the higher core count create much more heat at same clock speeds.
How fast a CPU/GPU actually is made up by 3 factors, IPC rate, clockspeed, and how many cores.
In case of the nvidia Ti vs non-Ti models, each core is the same in regards to IPC per core . Therefore, the higher speed of the Ti GPU is archived with more cores which lead to much larger die sizes which run hotter. In order to compensate for the higher power needs and heat built up of the larger die, this will compensated with lower clock speeds. So the factory base and OC clocks of Ti cards are usually slower than those of the non-Ti counterparts. Even so the Ti cards are much faster cards.
When you compare 2080 to 2080Ti: 2080 Ti is about 40% faster than the non-Ti, but it runs with much lower clock speeds than the 2080.
Also, the last 100 or 200Mhz in extra speed create the most heat! The heat curve is not linear!
I hope I was able to explain that.
In Short: Ti version are much faster, but not due to clock speeds. non-Ti models usually can achieve higher clock rates, since its a smaller die that needs less power and cooling.
