Testing (continued):

Unigene Heaven v2.1:

Unigenewas one of the first companies to release a DirectX 11 capable video benchmark, which was available shortly after Windows 7 was first released. They are now up to revision 2.1 of their Heaven benchmark, and it is the next test we will use to analyze the performance of the cards on hand. Two results are provided with the Heaven benchmark, Scores and FPS, and higher values are better for both.



The chart for FPS (frames per second) shown above doesn't do much to differentiate the cards, other than the HD5850 lagging behind by 4 FPS. 27 FPS seemed to be the ceiling in this test, and we'll have to call it a tie between the HD5870 and the HD6870.



Switching to the results for "Scores", we may have different values for the HD5870 and HD6870, but they are so close that I'd still be inclined to call it a tie.
