Benchmarks: Aliens vs. Predator, Far Cry 2
We used the custom DX11 benchmark for Alien vs. Predator as it's highly demanding. We played through a test scene in the same sequence every time for accurate results. The maximum possible visuals were enabled along with 4xAA/16xAF.
At 1920x1200, the Radeon HD 6870 was 11% slower than the Radeon HD 5870 and 7% faster than the Radeon HD 5850. Moreover, the Radeon HD 6870 outperformed the GeForce GTX 470 by 10% and the GeForce GTX 460 (1GB) by 23%.
Far Cry 2 Benchmarks
To test Far Cry 2, we used the "Action Scene" from the custom benchmark tool, which we feel is an excellent representation of real gameplay performance. We ran this DirectX 10 title at maximum in-game quality settings with 8xAA.
Although it didn't heavily trounce the competition, the Radeon HD 6870 performed very well in Far Cry 2, averaging 60fps at 1920x1200. AMD's new card proved to be 4% slower than the Radeon HD 5870 and 9% slower than the GeForce GTX 470. Meanwhile, it was 8% faster than the Radeon HD 5850 and it matched the performance of the GeForce GTX 460 (1GB).
