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 turns out to be quite an ordeal for the entry-level cards. The Radeon HD 6670 has the highest score since the Turks is superior to the Redwood architecture from nearly every aspect. The Radeon HD 6570 is impressive as well, being 26% faster than the Radeon HD 5670.
Benchmarking entry-level graphics cards in 3DMark Vantage is quite a torment. The graphics cards are visibly working at their limit. The Caicos architecture is more progressive compared to the old Radeon HD 5450, but the Radeon 6450 cannot score even 1000 points.
We use the Extreme profile here. As opposed to 3DMark Vantage, this profile uses a resolution of 1920x1080 pixels.
Having more TMUs, the Radeon HD 5670 beats the newer Radeon HD 6570, but the senior Turks-based product is in the lead, scoring 550 points. The Radeon HD 6450 is twice as fast as the Radeon HD 5450.
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! It is also Nvidia-optimized.
Save for the junior models, the graphics cards are fast enough for playing this game.
Take note that the old GeForce GT 430 is close to the new cards from AMD. This is the result of Fermi-based optimizations in the game engine.
Unigine Heaven Benchmark
We use Normal tessellation in this test.
The AMD Radeon HD 6670 is unrivalled in this benchmark. It is followed by the Radeon HD 6570 and Radeon HD 5670 which are 20% slower. The GeForce GT 430 is somewhere in the middle whereas the cheap Radeon HD 6450 and HD 5450 are slow.
