In this comparison category, the framerates from all the benchmarks were normalised against the highest scoring card and multiplied by 100, to give an index score on a 100 scale. The individual index scores from each benchmark at 1680x1050 and 1920x1200 resolutions were then averaged to give an overall performance index score across all benchmarks.
The benchmarks that were measured in each review are as follows:
- Knights of the Sea
- Call of Duty 4
- World in Conflict
- Call of Juarez
- Company of Heroes
Performance - Stock speeds
Performance - Overclocked speeds
It's comes as no surprise that the latest dual GPU cards, the Palit 9800GX2, and Sapphire 4870X2 score the highest. At the same time, it's interesting to see how close the single GTX260 and GTX280 cards compare in terms of performance, despite them being priced lower than the performance leader, the Sapphire 4870X2. The most surprising result of this comparison, to me, is how the 9800GX2 is neck-and-neck with the 4870X2, especially when overclocked, even though it costs considerably less.
There is a loose rule-of-thumb that the higher priced cards are the best performers. Remember that the cards are ordered in the graphs by ascending price. As the prices increase, the performance doesn't necessarily increase proportionately as sometimes you get less performance! So let's take a look now at the performance when taking the cost of the card into consideration.
