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 in the 3DMark DXR featuretest, the extra clock speed on offer from the MSI Gaming X and Inno3D Twin X2 helps boost performance, but even the Gaming X is not more than 3% faster than the Gigabyte Eagle.
