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 of Microsoft's DirectX 9. The previous version 3DMark03, did a nice introduction into this level of 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 in stores can only score
around 5000 3DMarks, whereas the worst card that meets the programs 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 future first-person shooter game with all the high details that entails. The dynamic shadows, high-detailed environment and advanced lighting techniques ensure that under normal circumstances, no recent card can run it with decent frame rates.
Game Test 2 - Firefly Forest
A forest gets filled with magic fireflies in the 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 not so far, 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.
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 "last resort" afterburners of the airship.
This scene is fairly complex with large areas of water reflecting the high canyon walls. The water actually is 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 actually look deep down in the water. The air in this scene also uses a volumetric fog, making distant cliffs of the canyon really look far away.
In some games, 3DMark05 seems to work better with the Dual GPU card than with two cards. The Extreme N7800GT card has an advantage over SLI cards. The memory works better (faster) with the Dual GPU card, because in the case of SLI, memory has to be synchronized through the mainboard, and this might cause some delays in performance, especially from mainboard to mainboard. The end result is that the throughput is not as high.
3DMarks on 3DMark05 are now calculated by 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. This means that all game tests are now equal.
The Dual-Core concept gets really close to SLI performance. The total score of 11348 is high enough when we considering that this is the score of dual 7800GT GPUs, while two 7800GTX GPUs in SLI could only get about 100 3dMarks more.
