However, it all depends how many rays per pixel you do. Apparently Vega & Pascal TX can do 4.88Grays at 1 ray per pixel maintaining 4K 60fps. (bit more fps on the TXp). Then are variations depending the hardware. You can do 2 rays per pixel at 10Grays at 4K 60fps. But do not expect Star Wars video quality here. And can do 200 rays per pixel at 1080p 24fps and the image quality is the one from the Star Wars and other videos..... That is why on the gaming Turing presentation Jensen didn't mentioned anything about Rays Per Pixel, like he did on the RTX8000 presentation who clearly said 200 rays per pixel.
