3D Mark is a widely used and accepted benchmark that stresses the DirectX performance of a VGA card. A very strong point of 3DMark is that it's VGA card measuring is does not require any CPU power. So the resulting fps are a good reference a VGA card's rendering performance. For testing the performance of each card we used the 4 game benchmarks 3DMark has.

3Dmark03 also includes sound and CPU tests as well as some other feature tests.

- Game Test 1 - Wings of Fury (DX7)

This test is a combat flight simulator written for older hardware (DirectX 7). Particles are used a lot in this test - smoke and vapor trails, flak and gunfire, and explosions are produced using point sprites and quads.

- Game Test 2 - Battle of Proxycon (DX8)

This test is a simulation of first person shooter game types. 1.1 and 1.4 Vertex shaders are widely used since all character models are skinned using vertex shaders.This makes this test a good vertex shader comparison for VGA cards.

- Game Test 3 - Trolls' Lair (DX8)

This test should be the favorite of all RPG lovers. It is a cut scene of a female warrior facing two malicious trolls. Again the same vertex and pixel processing is used as in game test 2.

This test also uses post-processing effects, such as Depth of Field and Bloom effects which are widely used in today's game cut scene sequences.

- Game Test 4 - Mother Nature (DX9)

Mother nature represents the level of effects and realism that are possible using 2.0 vertex and pixel shaders, plus some other features that DirectX 9 offers.

In 3DMark03, the 6600GT forges ahead of the X800 in the first three benchmarks which test DX7 and DX8 code. However, the X800 saved the best for the DX9-based GT4 test, where it yielded 5 fps more than the 6600GT.

If you test your machine with 3DMark, you can post the results at 3DMark's online result browser. For more information visit futuremark.com.

The scores in Futuremark's 3DMark03 show Connect3D's X800XL dominating over both the other cards. Second once more by a small margin is the 6600GT with the X800 just 300 3dmarks behind.
