The Test Bed is shown below:
Core 2 Duo Extreme Edition X6800
Zotac 8800GTS 320MB SLI
* Drivers used for NVIDIA Cards are Forceware 97.92 for 8800 series and 93.71
for 7950GX2 *
* Drivers used for ATi 1950XTX is Catalyst 7.2 *
I pit the cards against each other, turning on Anisotropic Filtering to 16x
and High Quality Textures, but without Anti-Aliasing. In my opinion AF
does a lot more for image quality than AA.
Same thing for ATi X1950XTX:
All games were ran at maximum quality settings.
Before we get into the testing, let us compare the difference between the Zotac 8800GTS 320MB and EVGA 8800GTS 320MB SuperClocked. Now below, you see that the Zotac’s Core clock is at 567MHz, Shader at 1188MHz and Memory at 900MHz.
On the other hand, EVGA 8800GTS 320MB Superclocked runs at 576MHz Core, 1350MHz Shader, and 837MHz Memory.
So in conclusion, the Zotac Card is:
10MHz Slower in Core
162MHz Slower in Shader
But 63MHz Faster in Memory
It will thus be interesting to see which side would outweigh which when we look at the performance figures later. Now, since I have only one Zotac 8800GTS 320MB, in order to insert in SLI results, I put the EVGA 8800GTS 320MB Superclocked together with Zotac to run SLI:
In this case with 2 different clocked cards, SLI actually runs both cards according to the primary output card’s BIOS, the Zotac. So SLI runs the 2 cards at 567MHz Core clock, 1188MHz Shader and 900MHz Memory. Just like the Zotac.
