How useful would hybrid CPU+GPU rendering be for real time Ray tracing?

[Cat Merc]

Lisa Su's very heavy hint at 16 cores on AM4 with Ryzen 3000 got me thinking. Assuming things keep on the same trajectory (bold assumption, but bear with me here) by 2022 we'll have 32 cores available as the top end on mainstream. Assuming that, how viable would a hybrid raster and Ray tracing renderer be using the massive amount of cores on the CPU?

You have to reverse assign what is needed.

Ray Tracing only adds eye-candy and is in it's infancy. Heck even geometric rays (ie: shapes) for lighting can add in processing using hybrid approach. So how many rays are needed in a typical game..? Then build out the imaginary hardware needs from there.


Personally, I think ROPS matter more than tensor cores, or ray tracing specific hardware. As for the CPU? I am not sure how integral the CPU will be, rasterization in games.
