3DMark - Port Royal
Port Royal is the first benchmark dedicated to real-time Ray Tracing. You can use Port Royal to test and compare real-time ray tracing performance on any graphics card provided you are running the correct version of Windows 10 and Microsoft DirectX Raytracing.
Unlike with other 3DMark benchmarks Port Royal is only a single scene and focused completely on GPU performance.

It would have been nice to see what the RTX 2080 Ti did in this benchmark however, the results would be the same. The RTX 3080 Ti is just walking away from the competition.
