Performance in Theoretical Tests

Scene Fill Rate

The GeForce 8800 GTX behaves in a predictable way in this test. In ordinary terms, the chip has 32 TMUs and 24 ROPs and this helps it beat the last-generation solutions. As for working with the Z-buffer, the G80 GPU is known to be able to process a double number of Z-values per cycle with enabled 4x multisampling and up to 192 Z-values when FSAA is disabled. We don’t use FSAA in our theoretical tests, so we’re dealing with the second operation mode here.

So, it’s all right with the fill rate of the GeForce 8800 GTX card. It is about 33% faster than the GeForce 7900 GTX even in the hardest case, which is expectable considering the difference in the number of their TMUs and ROPs and the increased memory bandwidth of the newer solution.
