Performance in Synthetic Benchmarks
There is no advantage from the increased GPU and memory frequencies of the GeForce 9800 GTX card when it comes to the overall scores. The difference between the two versions of this graphics card is a mere 73 points, which is within the measurement error range.
It’s different in the individual tests: the Zotac doesn’t show much in the first test, but the overclocked frequencies give it an edge over the reference card starting with 1600x1200 resolution. The advantage is not high, amounting to 6-8%, which is not enough to compete with the Radeon HD 3870 X2 that wins two out of the three 3DMark05 tests by a large margin.
