Tessellation performance
Hardware-based tessellation is a cornerstone of DX11. The ability to efficiently generate massive geometry and then to apply what's known as a displacement map to it makes it a tasty technique for adding complexity and detail to a scene without a huge computational cost.Unigine's Heaven 2.0 benchmark tests the ability of DX11 GPUs to provide varying levels of tessellation and extra in-benchmark detail.
Here's the standard benchmark run at 1,920x1,200 with 4x AA and 16x AF. Hover your mouse over the picture to see the difference between no tessellation and moderate tessellation.
Benchmarks
It takes until the extreme benchmark until the GeForce GTX 480 is able to pull ahead, just, and two HD 5850 cards, which literally double performance in CrossFireX at all settings, continue to beat the HD 5970.
