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).
As for 3DMark's DXR feature test, here the GameRock OC uses its increased power and frequency headroom to come in 5% ahead of the Gigabyte Eagle OC. This makes it twice as fast as AMD's finest, the 6900 XT.
