ASUS A8N-SLI Deluxe - Page 7
With 3DMark05, Futuremark continues the tradition in its benchmarking software by providing a state-of-the-art Microsoft ® DirectX ® 9 3D performance benchmark.
3DMark05 is an all new 3DMark version, making the most out of Microsoft's DirectX 9. The previous version, 3DMark03, provided a nice testbench for this technology. However, 3DMark03 used DirectX 9 specific features in a limited manner, because fully supporting hardware was rare at the time of its launch. In contrast, 3DMark05 requires DirectX 9 hardware with full support for at least Shader Model 2, and takes shader usage to never before seen levels.
Just like its predecessors, 3DMark05's point system is set so that at the moment of release, the high-end VGA cards available on the market can only score around 5000 3DMarks, whereas the worst card that meets the program's requirements, yields a score of 1000.
Game Test 1 - Return to Proxycon
Being the sequel to the "Battle of Proxycon" from 3DMark03, in "Return to Proxycon" we're once again set in space and the battle continues as space pirates invade a cargo ship in order to take control of its valuable cargo.
This test, tries to simulate a futuristic first-person shooter game with all the high details that such a game entails. The dynamic shadows, highly detailed environment and advanced lighting techniques, ensure that under normal circumstances, no recent card can run it with decent frame rates.
In this test, with the two cards combined, the performance is similar to a 6800Ultra GPU. The second 6600GT processor certainly manages to accelerate all the dynamic shadows and advanced lighting processing.
Game Test 2 - Firefly Forest
A forest is filled with magic fireflies at night. The moon is nearly full, illuminating the forest with a bluish faint light. The magic fireflies have flickering, bright green lights that playfully move around the forest.
This scene is a nice example of a smaller scale outdoor scene with rich vegetation. Immediate visibility is only short range, and there is a skybox surrounding the whole scene.
A large number of trees with their branches swinging separately, and dense vegetation being dynamically distributed according to the camera movements, make this test the most demanding of the three.
With this game test, the two Extreme N6600GTs performed even better, giving 18fps while the 6800Ultra was stuck at 15.1. It should be noted that we expected the Multi-GPUs performance to be better than a single ASUS 6600GT, but we did not expect such a big difference. Llet's carry on with these game tests to get the full picture with the SLI performance.
Game Test 3 - Canyon Flight
A Jules Verne type airship flies through a canyon guarded by a dangerous sea monster. The airmen defend their ship using heavy cannons, but these seem to have no effect on the huge sea monster. Finally, the crew manages a narrow escape using the airship's "last resort" afterburners.
This scene is fairly complex with large areas of water reflecting the high canyon walls. The water is actually one of the key points of interest in this scene. The water not only does realistic looking reflections and refractions, it has a depth fog, making the sea monster swimming under the airship appear deep down in the water. The air in this scene also uses a volumetric fog, making distant cliffs in the canyon appear far away.
Same picture here, with the SLI enabled cards giving an extreme 32fps. Excellent performance by ASUS.
3DMarks on 3DMark05 are now calculated with the following formula:
(Game Test 1 * Game Test 2 * Game Test 3)^0.33 * 250
This is basically the geometric mean of the total frames in each game multiplied by 250, which means that all game tests are on an equal par.
Let us now see the results for the two ASUS Extreme N6600GT cards:
Since the dual GPUs managed to outperform its competitors in all test, its reasonable that it receive the highest 3DMarks.
