Crytek released a Ray Tracing demo using their latest Cry Engine. It doesn't require a powerful RTX graphics card to run. Also, AMD GPUs use asynchronous compute, which does handle that sort of workload better than a non-RTX Nvidia GPU.
You can see here that it's barely putting any stress on my i9 9900k, but it is taxing the GTX 1080 @ 1440p.
