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.
Ultra heavy weight Radeon HD 6990 graphics card laughs at 3Dmark Vantage calculations. We can safely assume that a shift in the GPU architecture provided significant performance improvements for AMD devices with around 20% performance increase over the previous generation. Enhance mode comes mere 600 points shy from the physiological 20,000 mark.
The previously seen tendency continues in 3DMark Vantage game tests. While in the popular 1600x900 resolution the gap between Radeon HD 6990 and Radeon HD 5970 is only at 8%, it quickly changes to almost 27% domination in 2560x1600. Unfortunately for Nvidia, its current most powerful GeForce GTX 580 runs only half as fast as the opponent.
Once again our hopes were with Radeon HD 6990 in 3DMark11 benchmark. This particular piece of software is the hardest test yet and our today's hero has much to prove here. At first it may seem that 3000 points is not a lot to be proud of but if you compare that to struggling GeForce GTX 580 with its 1959 points you will have to treat Antilles-based solutions with respect. At least until competition finally beats them.
Tom Clancy’s H.A.W.X. 2
The controversial Tom Clancy’s H.A.W.X. 2 combat flight simulator benchmark makes heavy emphasis on tessellation. Once again fine-tuned architecture of GeForce GTX 580 allows it to fight Radeon HD 6990 as an equal. From the numbers it is also evident that AMD's work on its tessellation unit has not gone unnoticed as our hero has no problem outperforming Radeon HD 5970 which is based on the previous GPU architecture.
Unigine Heaven Benchmark
A few weeks ago Ungine has released an updated version of its demo. The newly released Ungine Heaven benchmark is now a version 2.5 and offers a few extra tasks for the GPU to process.
The benchmark may use a lot of tessellation algorithms but surprisingly it is AMD designed solutions that come out victorious here. Both: Radeon HD 6990 and, which is even more surprising considering its weaker tessellation unit, Radeon HD 5970, leave opposition lagging behind. The test is a mere synthetic benchmark, but as its engine is for sale we might actually see some games based on it in the future.
