Benchmarks: Dawn of War, Far Cry 2
The Radeon HD 5830 performed considerably better than previous generation Radeon cards when testing with Dawn of War II. At 2560x1600 the card saw an average of 40fps which allowed it to match the GeForce GTX 275, while trailing the GeForce GTX 285 by a 7% margin. Furthermore, while the Radeon HD 5830 may have been 17% slower than the 5850, it was still 25% faster than the Radeon HD 4890.
Frame rates in Far Cry 2 were very low across the board, much they were when testing with Crysis Warhead. We should note however that for this test 8xAA is enabled, which has a significant impact on performance. As a result the Radeon HD 5830 averaged just 36fps at 1680x1050 and 20fps at 2560x1600. This meant that the card was 29% slower than the Radeon HD 5850 and GeForce GTX 285.
