Raytracing and Path Tracing are both rendering techniques that aim to simulate realistic lighting in games. While runnable on most relatively modern day cards (>2016), Nvidia cards, especially 40 and 50 series Nvidia cards, are much better at calculating the light scenes necessary for ray/path tracing. In combination with other excellent Nvidia features, like their upscaler and multi-frame generation, ray/path tracing are possible for the 5070, even at 4k.
