The Codecreatures Benchmark is a demo for new game engines that make strong use of pixel and vertex shaders and therefore have very high resolution textures. The GeForceFX clearly wins with its average frame rate scores. By contrast, the Radeon scores with its average polygon count (avg MPolys/s) results.
Conclusion: Standard Gaming Benchmarks
In the standard tests (without FSAA and anisotropic filtering) the GeForceFX comes out on top. As resolution increases, however, its lead decreases.
