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).
3DMark’s DXR feature test is an intensive benchmark that is entirely ray traced. We know from months of testing that AMD’s 1st generation of hardware accelerated ray tracing isn’t at the same level as Nvidia’s 2nd generation implementation found in its Ampere GPUs, so it’s not a surprise to see the 6600 sitting bottom of the pile, slower than even the RTX 2060 by a whopping 31%.
