Performance Summary Diagrams
Here is a table with the test results:
Now let's check out the summary diagrams.
The summary diagrams show the performance of the graphics cards at their default frequencies. The first of them is indicative of the advantage of the new Radeon HD 6790 ($149) over the Radeon HD 5770 ($129) where the latter's speed serves as a baseline. The dotted line marks the difference in their recommended prices which amounts to 15.6%.
So, the Radeon HD 6790 is an average 15% ahead of the Radeon HD 5770 without FSAA and 13% ahead with 4x or 8x MSAA. The new card enjoys the biggest advantage in Unigine Heaven Demo, Left 4 Dead 2 and Tom Clancy’s H.A.W.K. 2. The smallest advantage can be observed in F1 2010 and in the FSAA-less mode of StarCraft II: Wings of Liberty and Mafia 2.
The next diagram shows how slower the Radeon HD 6790 is against the Radeon HD 6850.
Thus, the Radeon HD 6790 is an average 13% and 18% slower in the FSAA-less and FSAA modes, respectively. Although these numbers are somewhat higher than the Radeon HD 6790’s advantage over the Radeon HD 5770, we can see that the new card fits in nicely between the two older products.
Now let’s compare the two direct rivals: AMD Radeon HD 6790 and Nvidia GeForce GTX 550 Ti.
The diagram makes it clear that the Radeon HD 6790 is inferior to the GeForce GTX 550 Ti in but a few tests, namely Far Cry 2, Lost Planet 2, Tom Clancy’s H.A.W.K. 2 and in the high-quality mode of StarCraft II: Wings of Liberty. The two cards are equals in Resident Evil 5 and Borderlands. The rest of the tests are won by the new card from AMD which enjoys an advantage of up to 30%. The Radeon HD 6790 is an average 13.3% ahead of the GeForce GTX 550 Ti across all the tests in the FSAA-less mode and 4.8% ahead in the FSAA mode.
And the final diagram compares the Nvidia GeForce GTX 460 with the AMD Radeon HD 6850. I’ll leave it uncommented.
