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).
The 3DMark DXR feature test is more worrying however, with the 7900 XT slower than even the RTX 3080 10GB. The RTX 4080 is almost twice as quick in the same test.
