Single Card Results
Doom 3
At 68.4 fps, the new GeForce 7600 GT was just 11.7% slower than the GeForce 7800 GT and about 20% slower than the GeForce 7800 GTX and GeForce 7900 GT. Pretty remarkable performance for a card that's much cheaper than its competitors in this comparison!
When 4x anti-aliasing was enabled, its performance gap with the GeForce 7800 GT increased to 23.3%. It also fell back against the GeForce 7800 GTX and GeForce 7900 GT with a difference of 32% and 35% respectively.
There were no change in frame rates for all three cards when Transparency Anti-Aliasing was enabled. Presumably, it has no effect at all in Doom 3.
Quake 4
Surprisingly, in Quake 4, the GeForce 7600 GT actually beat the GeForce 7800 GT! Although the performance advantage was small at just 4.7%, it was still a notable victory for this mid-range card.
However, it was 24% slower than the GeForce 7800 GTX and 27.5% slower than the GeForce 7900 GT.
When 4xAA was applied though, its performance dropped quite a bit. It lost its lead over the GeForce 7800 GT and was 9% slower. It was also 31% slower than the GeForce 7800 GTX and 35% slower than the GeForce 7900 GT.
Like in Doom 3, there was virtually no difference in the performance of all three cards when TAA was enabled.
3DMark 06
The new GeForce 7600 GT achieved a score of 3002 points in 3DMark 06 with this testbed. It was 14% slower than the GeForce 7800 GT and about 24% slower than both GeForce 7800 GTX and GeForce 7900 GT. A good score for this mid-range card.
The same results were reflected in the Shader Model 2.0 test.
As well as the SM 3.0 test.
