Comparison of Graphics Chips and Introduction of the Test Configuration

GPU vs. CPU Upgrade: Extensive Tests
By

The Geforce 6 and 7 are not overclocked. If the Geforce 8800 GTS 512 OC was to be operated at the standard clocking rate, it would be as fast as the Geforce 8800 GT OC in terms of overall performance. The Geforce 9600 GT has 1024 MB of graphics memory, while the new Geforce 9800 GTX is competing for first place with the Geforce 8800 GTS 512. Which of these two models comes out on top depends on the clocking rate used—the two cards are too similar in terms of the technical specifications and clocking rates with G92 graphics chip, for any relevant performance differences to be identified.

Nvidia Graphics Cards
Card manufacturer and chip Code name Memory Shader GPU Speed Memory Data Rate
Geforce 9800 GTX G92 512 MB GDDR3 4.0, 1688 MHz 675 MHz 2200 MHz
Geforce 9600 GT OC G94 1024 MB GDDR3 4.0, 1680 MHz 700 MHz 1900 MHz
Geforce 8800 GTS OC G92 512 MB GDDR3 4.0, 1825 MHz 730 MHz 1944 MHz
Geforce 8800 GT OC G92 512 MB GDDR3 4.0, 1650 MHz 660 MHz 1900 MHz
Geforce 7950 GT G71 512 MB GDDR3 3.0 550 MHz 1400 MHz
Geforce 6800 GT NV40 256 MB GDDR3 3.0 350 MHz 1000 MHz

OC = overclocked (speed is higher than standard)
Memory Data Rate = physical clock rate times two

For the purpose of testing, all graphics cards used a version of the new 174 driver introduced with the 9600 GT. The Geforce 9800 GTX required Version 174.74 because the graphics chip was not included in official releases. The Microsoft Flight X SP2 and DX10 preview modes still have representation errors in the water pixel shader—as a result, the simulated waves are missing. In DX9 mode (Geforce 6 and 7) everything appears to be fine.
