Gaming Benchmarks: Unreal Tournament 2003
Settings: Texture Detail: Highest, World Detail: Highest, Character Detail: Highest, Physics Detail: Normal, Character Shadows: ON, Dynamic Lighting: ON, Detail Textures: ON, Projectors: ON, Decals: ON, Coronas: ON, Decal Stay: Normal, Foliage: ON, Trilinear Filtering: ON. We ran the Antalus flyby-scene.
In 1280x1024 and 1600x1200 resolutions, where the CPU and the overall system performance do not tell that much on the graphics card speed, NVIDIA GeForce FX 5900 Ultra manages to get slightly ahead of GeForce FX 5800 Ultra. ATI RADEON 9700 Pro and ATI RADEON 9800 Pro fall behind.
When we enable full-screen anti-aliasing, the results are determined by the graphics bus bandwidth in the first place. That is why the cards with 256bit memory bus leave GeForce FX 5800 Ultra with its 128bit memory bus behind. The leadership belongs to NVIDIA GeForce FX 5900 Ultra, of course, due to its enormous memory bus bandwidth.
However, as soon as anisotropic filtering is on, the memory bus bandwidth no longer plays the crucial role. As a result NVIDIA GeForce FX 5800 Ultra catches up with the newcomer due to higher core frequency: 500MHz against 450MHz by GeForce FX 5900 Ultra.
ATI RADEON 9800 Pro appears just a little slower than NVIDIA GeForce FX 5800 Ultra and GeForce FX 5900 Ultra when they work in Quality mode, however, RADEON 9700 Pro with considerably lower clock frequencies falls quite far behind them.
When we force anisotropic filtering and full-screen anti-aliasing, the memory bus bandwidth starts influencing the results together with the anisotropic filtering speed. And the higher gets the screen resolution, the bigger grows this influence. As a result, NVIDIA GeForce FX 5900 Ultra gets farther ahead of the predecessor as the resolution grows up. ATI RADEON 9700 Pro and ATI RADEON 9800 Pro, which also feature high memory bus bandwidth manage to outpace NVIDIA GeForce FX 5800 Ultra in high resolutions.
