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.
While there's no specific ray tracing hardware that forms part of the 1660 SUPER GPU, the card does support Microsoft's DXR API – so it can run 3DMark Port Royal. As you'd expect, the results aren't a scratch on the RTX 2060 – which has proper RT cores – but the new memory does help the card score above the 1660.
