Performance in Synthetic and Semi-Synthetic Benchmarks
Futuremark 3DMark Vantage
We minimize the CPU’s influence by using the Extreme profile (1920x1200, 4x FSAA and anisotropic filtering). We also publish the results of the individual tests across all resolutions.
The Radeon HD 6870 scores more than 8000 points overall, surpassing the score of the GeForce GTX 470. The Radeon HD 6850 is in between the two versions of GeForce GTX 460.
The Radeon HD 6800 series is much better in the second test than in the first one, especially the senior model. That test needs high geometrical performance, so this might have been expected. However, we already know from the gaming tests that this is not enough to beat the opponents from the GeForce team.
Final Fantasy XIV Official Benchmark
This benchmark produces an incomprehensible result in points, so we use Fraps to get more understandable numbers. It can only run at 1280x720 and 1920x1080.
We don’t see anything new in this test. It still prefers the Radeon architecture. We can only note that the Radeon HD 6870 is as good as the Radeon HD 5870 at 1920x1080.
Unigine Heaven Benchmark
We use Normal tessellation in this test.
Despite the improved tessellation subunit, the Radeon HD 6800 family doesn’t improve the performance of AMD’s solutions in this benchmark, except for 1920x1080 where the senior model is ahead of the Radeon HD 5870 in terms of bottom speed. Does it mean the Barts is insufficiently effective at complex tessellation or there are some other performance-limiting factors? Whatever the reason, the Radeon HD 6800 series isn’t brilliant in this test.
