Ray Tracing and GPU Memory Requirements

I've been reading a lot about ray tracing tech here in the forums, but I'm still not sure how a ray traced game would affect the memory requirements for a GPU.

As I understand it currently, entire scenes are required to load into GPU to process a ray traced scene, but does that require you to ensure a higher max GPU memory limit then?

For instance, assuming other GPU performance is up to par, how would an 8GB card handle a 4K HDR fully rendered ray traced scene?

Thanks
 
I don't know how much memory the BVH will require, but hybrid rendering will use more memory than rasterization alone. The final resolution and HDR may not matter much as the BVH is resolution independent.
