Real-time ray tracing is incredibly demanding. The latest graphics cards have dedicated hardware that’s optimized for ray-tracing. The 3DMark DirectX Raytracing feature test measures the performance of this dedicated hardware. Instead of using traditional rendering techniques, the whole scene is ray-traced and drawn in one pass. The result of the test depends entirely on ray-tracing performance. (UL).
Ray tracing isn't a huge boost for the RX 6X50 series either, as it doesn't have any extra RT cores or streaming processors to aid with BVH traversal. Instead, the only increase in ray tracing performance comes due to the increased clock speed, and performance scales similarly to 3DMark Time Spy.
