Performance in Synthetic Benchmarks

Futuremark 3DMark05 build 1.2.0

In the total score chart Gigabyte X1900 XTX outperforms its brother based on G71 GPU by 527 points. Let’s see what results we will get from the individual tests. However, we should keep in mind that the individual test results were obtained with enabled anti-aliasing unlike the total score.

Game 1 test is the largest one and contains a lot of light sources, however the Gigabyte solution based on ATI R580 shows the best result here than the Nvidia G71 card with 24 TMUs. It should be the ringbus memory controller of Gigabyte Radeon X1900 XTX that played the most important part here.

Game 2 test doesn’t require high fillrate, but demands efficient work with lightning and shadows, as well as performance of vertex processors that are responsible for creating dynamic vegetation. Thanks to higher GPU speed, Gigabyte GeForce 7900 GTX manages to show very good result in 1024x768, but then it start falling behind Gigabyte Radeon X1900 XTX again. In 1600x1200 the gap reaches 10%.

Game 3 test requires high complex shader processing speed, and here Gigabyte X1900 XTX is beyond all competition right from the start, because it features 48 pixel processors onboard, which is twice as much as Gigabyte GeForce 7900 GTX has. The triumph of Radeon X1900 is slightly held back by the 16 TMUs it has, because the scene has very high math1ematical as well as texturing workload. All in all, the total score demonstrated by the Gigabyte graphics cards in 3DMark05 test is proven by the results of each individual benchmark.
