3DMark Port Royal is the world’s first dedicated real-time ray tracing benchmark for gamers. You can use Port Royal to test and compare the real-time ray tracing performance of any graphics card that supports Microsoft DirectX Raytracing. As well as benchmarking performance, 3DMark Port Royal provides a realistic and practical example of what to expect from ray tracing in upcoming games.
In the ray tracing-specific Port Royal benchmark, the 2080 SUPER scores about 400 points more than the RTX 2080, though the 2080 Ti is still 1600-odd points ahead.
