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).
3DMarks’ DXR feature-test is a tough test of a GPU’s ray tracing abilities. Despite the significant increase to memory bandwidth, the RTX 3070 Ti only has an extra two RT cores compared to the RTX 3070, and is just 1% faster in this test.
