Many use ray tracing and path tracing interchangeably and consider path tracing to be a form of Ray tracing (Old school RT would be called Whitted Ray Tracing).<p>Single bounce ray tracing isn&#x27;t very interesting, what we want is real time global illumination such as with park tracing. For simple scenes this is possible on a gpu today, at least with low res and a reasonable amount of noise. If this chip can do with a million triangles what a gpu does today with a hundred, then it&#x27;s very interesting (not saying it can).<p>Real time gpu PT today:
