Futuremark 3 DMark06 build 1.0.2
All versions of the GeForce 7600 GT, including the Gigabyte GV-NX76T256D-RH, look much better in 3DMark06 than in the earlier version of 3DMark. The Gigabyte reaches the level of the Radeon X1800 XL at the overclocked frequencies.
The first group of tests makes use of Shader Model 2.0. The Gigabyte GV-NX76T256D-RH is much faster than its opponent here. The results of the separate tests will explain why.
The Gigabyte is a little slower than the Radeon X1800 GTO in the SM3.0/HDR tests. It is also unable to compete with the Radeon X1800 XL at the overclocked frequencies as it did in the SM2.0 tests.
Mainstream graphics cards are too slow in 3DMark06 if used with enabled full-screen antialiasing, which increases the measurement error. That’s why we decided not to benchmark them in the “eye candy” mode, limiting ourselves to anisotropic filtering only. Moreover, the GeForce 7 family cannot use HDR (FP16) and FSAA simultaneously.
The results of the first SM2.0 test are good enough for a solution with only 12 pixel processors, 12 TMUs and 8 ROPs: the Gigabyte GV-NX76T256D-RH isn’t any worse than the Radeon X1800 XL. It is close to the Radeon X1900 GT in 1280x1024 and even outperforms it at the overclocked frequencies.
The second SM2.0 test is technically similar to the second game test from 3DMark05, but the scene has been made more complex, so it is only in 1920x1200 that the Gigabyte card falls behind the Radeon X1800 GTO.
The first SM3.0/HDR test produces opposite results: the Gigabyte GV-NX76T256D-RH is slower than the Radeon X1800 GTO in 1280x1024 only.
Demonstrating dynamic shadowing and HDR capabilities, the second SM3.0/HDR test is quite favorable towards the Gigabyte GeForce 7600 GT. This card is as fast as the Radeon X1800 XL in 1280x1024 without any overclocking. It slows down to the level of the Radeon X1800 GTO in the higher resolutions, but not a step lower. So, the small advantage the Gigabyte GV-NX76T256D-RH enjoys over the Radeon X1800 GTO in the total scores is indeed confirmed by the results of the separate tests from the 3DMark06 suite.
