We've been able to do realtime ray tracing in software since forever though and the shadertoys and whatnot have been full of hardware accelerated demos, that's not so interesting.

I remember playing with a number of demos on my intel core 2 duo macbook (not pro) a decade ago.

They weren't doing that in hardware real time accelerated at 4k resolution in AAA games. This year they are. That's a big leap from your core 2 duo demos.

The new GPUs have hardware specifically designed to do the type of math that raytracing does, such as ray/volume intersections, faster or more efficiently than generic shader hardware. Sufficient quantity (FLOPS) can become a quality of its own.
