The RTX 2070 had the same launch price as the GTX 1080, and has somewhere around 10-15% better performance before you look at raytracing.
The boost at the same pricepoint was definitely not as much as previous generations, and the prices do seem to have got higher, but the performance per dollar also seems to have gone up.
Also to get that extra 10 to 15% performance, power consumption has also gone up even more so on the Super cards and when you look at the overclock-ability of the super based cards they are already pushed to limit just so Nvidia had something to show in performance for the refresh.
