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).
In a test of the GPU's ray tracing performance, the 3DMark DXR feature test sees the RX 6900 XT effectively matching the RTX 2080 Ti. This puts it 13% ahead of the RX 6800 XT, but 38% behind the RTX 3080.
