GeForce 6600 GT or RADEON 9800 XT?
As you have seen, the new family of mainstream graphics processors from NVIDIA has done well in real-life applications. Cutting it short, the GeForce 6600 GT definitely delivers more performance than the RADEON 9800 XT, and also provides more functionality.
Meanwhile, in the lower class, the RADEON X600 XT can still compete with the GeForce 6600 in terms of speed, but the latter seems to have a higher flexibility in terms of price.
We put the results of the gaming benchmarks all together into diagrams to get a notion of the performance level of the tested cards at a glance:
So, the GeForce 6600 GT wins 22 tests out of 32 in 1280x1024 resolution and 25 tests out of 32 in 1600x1200 resolution in its competition with the RADEON 9800 XT graphics card. This is just excellent for a simple graphics card with a twice-narrower memory bus. Its advanced architecture and higher clock rates proved to be of more weight, though, as the GeForce 6600 GT defeated the ex-leader RADEON 9800 XT in all the modern games like Doom III, Unreal Tournament 2004, Far Cry, Counter-Strike: Source and others.
The main accomplishment of the new GPU is its extremely high speed in games rich in complex geometry and shader-based effects. That is, the GeForce 6600 GT is perfectly suited for the kind of work it is supposed to perform. There will be ever more such “heavy” games in the future, so NVIDIA’s new mainstream GPU seems a better buy than the ex-top-end RADEON 9800 XT.
As for the junior, the GeForce 6600 model, it has pocketed a few victories, too. We can claim it is faster than the RADEON X600 XT, but don’t forget that it will have to face a much more dangerous enemy, the RADEON X700.
The results of the new products in the eye candy mode (4x full-screen antialiasing and the maximum possible level of anisotropic filtering) do not disappoint, either. They have 17 victories out of 25 possible in 1280x1024 resolution. However, the negative effect of the 128-bit memory bus is more perceptible here than in the pure speed mode. In the highest resolution, 1600x1200, the GeForce 6600 GT doesn’t boast any advantage over its closest competitor, which has a wider memory bus and uses efficient memory bandwidth utilization algorithms.
