Besides the increase in raw compute, what is materially different this time around?

Hardware acceleration of BVH traversal and tight integration with the shader cores to allow efficient scheduling of shader execution and new ray generation when ray hits are detected.

  The former is discussed here: https://devblogs.nvidia.com/thinking-parallel-part-ii-tree-traversal-gpu/ https://devblogs.nvidia.com/thinking-parallel-part-ii-tree-t...

    That's a software implementation though. These new cards have actual hardware specifically for that.
