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).
Likewise for the 3DMark DXR feature test, the RX 7800 XT is within a single frame of the RX 6800 XT, and only a touch behind the RTX 3070 Ti.
