Wrong, it refers to new dedicated logic on their GPUs for doing BVH traversal and triangle intersection, much faster than if you use the more general purpose shader units. The same way GPUs had dedicated logic for rasterisation to make that super fast (hierarchical z-buffering, interpolation and blending), now they have some for ray tracing.
