Synthetic Tests: Conclusion

There are some points we’d like to draw your attention to in the results of the GeForce 6600 GT in synthetic tests.

First of all, the new GPU boasts a highest efficiency of multi-texturing, which is indicative of a well-designed system of texture caches. The GeForce 6600 GT delivers slightly more than half the performance of the GeForce 6800 GT in this case, and this fully corresponds to the GeForce 6600 GT’s having twice less pixel pipelines but a higher core frequency.

At single-texturing or at writing colors only (without rendering textures), the GeForce 6600 GT feels the lack of the memory bandwidth that reduces the efficiency of the GPU. We shouldn’t regard this as a serious shortcoming of the GeForce 6600 family chips – in many modern games the load on the pixel processors consists of pixel shaders rather than of trivial texturing, and the speed of the memory subsystem ceases to be among the crucial performance-related factors.

So what about shaders? Cutting it short, the GeForce 6600 GT is excellent at executing them. Sharing the same architecture with the GeForce 6800 GT, but having twice less vertex and pixel processors, the GeForce 6600 GT utilizes its higher core frequency to get higher results than half the performance of the GeForce 6800 GT. It means the new GPU is faster than the ATI RADEON 9800 XT as well as the GeForce 5950 Ultra in a majority of relevant synthetic tests. We don’t even mention the feeble RADEON X600 XT and GeForce 5700/5700 Ultra with their 4 pixel pipelines.

Everything said about the GeForce 6600 GT can be applied to the GeForce 6600 with a correction for its lower clock rates.

So our synthetic tests reveal a huge potential of NVIDIA GeForce 6600/6600 GT GPUs, unattainable by mainstream graphics cards of the previous generation in terms of both functionality and – that’s the most attractive – speed. Moreover, the newcomers can even bear comparison with the previously top-end solutions, the RADEON 9800 XT and GeForce FX 5950 Ultra.

We’re finished with theory now, but that’s not all. In our next report we will run a bunch of modern games on the GeForce 6800/6800 GT to check out the real-life performance of these GPUs.
