Realtime ray-tracing is a mix of hardware acceleration for ray intersections and de-noising. The de-noising approaches are certainly novel and not really analogous to previous methods, imho, though the accelerated bounding box hierarchies for accelerating intersections certainly appear in previous iterations.

I think this is the key answer, de-noising, using various neural techniques finally allowed acceptable images to be produced from sometimes <1 ray / pixel, where normally images produced at such densities were nearly unusable.

This is still not perfect and many ray tracing techniques rely on accumulation over time which limits certain images from working (I imagine raytracing a small particle cloud, or fast shifting objects to be a worst case scenarios)
