Performance in Synthetic Benchmarks
It is only in the SM3.0/HDR tests that the Zotac shows higher performance than the reference card. There is almost no difference in the overall scores and in the SM2.0/HDR tests. This is logical since the SM3.0/HDR tests put an emphasis on the GPU’s computing resources.
When we enable 4x FSAA in the individual SM2.0 tests, we can see a difference of 4-6% between the reference GeForce GTX 280 and the overclocked version from Zotac.
The SM3.0/HDR tests agree with what we’ve seen above: the performance increase is higher at 7-12%. This confirmed the results of the gaming tests, indicating that the Zotac is about 10-11% faster than the reference card.
