Relief Rendering and Other Tests

The GeForce 7800 GTX is by far faster than the GeForce 6800 Ultra at rendering relief with the EMBM method, but is slower than the RADEON X850 XT Platinum Edition. The only exception is 1600x1200 resolution where the new GPU from NVIDIA wins.

NVIDIA’s graphics processors have always been excellent at rendering relief with the Dot3 method, and the G70 is not an exception. It is faster than the previous-generation solutions in all resolutions.

The Ragtroll test is an indicator of the balance of the CPU-driver-GPU chain. It uses the physics engine Havok, version 1.1 vertex shaders, and version 1.4 pixel shaders. The graph of the GeForce 7800 GTX goes almost in parallel to the graph of the RADEON X850 XT Platinum Edition, and both graphics cards look somewhat worse-balanced than the GeForce 6800 Ultra. As for the absolute fps rates, the GeForce 7800 GTX wins this test.
