Depends on the LOD and number of lights you want. You can get a better image than raster using only one or two shadow/reflection bounces and several lights. At 10 Giga rays, the 2080TI could do 166,666,666 rays per frame at 60fps. 4k screens have 8,294,400 pixels, so for every pixel you could have one initial ray with at maximum 19 shadow rays. Of course when you introduce a few reflection bounces etc. it becomes significantly less rays/pixel.
This would absolutely max out the RT cores to their theoretical limit, so I imagine we will stick with hybrid for a while but I think 1000x is an extreme estimate.
(Unless of course my math is wrong here.)
