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).
For an early indicator of ray tracing performance, the RTX 4080 averages 84.88 FPS in the 3DMark DXR featuretest. This makes it 37% faster than the RTX 3090 Ti, and 39% slower than the RTX 4090.
