3DMark11 is Futuremark's latest iteration of the video card software benchmark suite, building on the features of 3DMark Vantage and 3DMark 06 as well as earlier version. It's optimized and intended for testing DirectX-11 capable hardware running under Windows Vista or Windows 7.
3DMark Vantage offers benchmark tests focusing on GPU, CPU, and Physics performance. For this review I concentrated on the four GPU-specific tests. The first two tests take you through an undersea scene with small submarines exploring the sea floor and sunken ships. In the GT1 test, there's no tessellation, but there are extensive lighting and shadow effects. In the GT2 test, the same scene is repeated but with moderate tessellation and fewer lighting effects.
Here we see nice scaling with the NVIDIA cards. The Radeon 6970, AMD's previous top-end single GPU video card, turns in performance just between the NVIDIA GTX 570 and GTX 580. The dual-GPU Radeon 6990 beats the dual-GPU GTX 590, but both are trounced by the R7950 (when overclocked) and the R7970. Also notice how close the overclocked R7950 is to the $100-more-expensive R7970. We'll see a lot of this in subsequent benchmarks.
Cost Analysis: GT1+GT2
The second pair of graphics tests explore an abandoned temple deep in a tropical jungle. The GT3 test has medium tessellation and one shadow-casting light, while the GT4 test ups the ante with heavy tessellation and many shadow-casting lights. The GT4 test is by far the most demanding of this test suite.
Cost Analysis: GT3+GT4
Test Summary: With AMD's new driver, the R7970 surges ahead of both dual GPU cards, as does the 7950 when overclocked (well, almost...it loses to the 6990 by 0.1 FPS).
