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 much tougher on AMD GPUs as we know, and the 7900 GRE lags behind even the RTX 3080 here, while it's not a whole lot faster than the RTX 4060 Ti 8GB.
