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.
3DMark Vantage suggests that the PowerColor PCS+ HD6770 Vortex II is the fastest representative of its product class. The aged architecture of the new card doesn’t reflect in its score as it beats the younger GeForce GTX 550 Ti. The extra overclocking helps the PowerColor score over 6000 points and almost overtake the Radeon HD 6850 which is more advanced architecturally.
We use the Extreme profile here. As opposed to 3DMark Vantage, this profile uses a resolution of 1920x1080 pixels.
3DMark 11 produces unexpected results. Nvidia proves to be unable to compete with the Radeon HD 6770 right now. The PowerColor was close to 1000 points when additionally overclocked, and we are sure some lucky sample of the card can beat that mark. AMD’s 2-year-old solution triumphs again!
Tom Clancy’s H.A.W.X. 2 Preview Benchmark
This benchmark makes wide use of tessellation to render the surface of the earth. The number of polygons per one frame can be as high as 1.5 million!
This synthetic benchmark reveals the downsides of the old architecture, even though the RV840-based solution delivers a high enough frame rate. The factory overclocking adds a few more frames per second to the PowerColor’s speed.
Unigine Heaven 2.5 Benchmark
We use Normal tessellation in this test.
Notwithstanding the superiority of the Fermi architecture in tessellation performance, the PowerColor card is competitive in this test. Unigine Heaven 2.5 draws very complex scenes, and the first game with Unigine technologies is already coming up. So, it is good that the PowerColor PCS+ HD6770 Vortex II is somewhat faster than the GeForce GTX 550 Ti at every resolution.
