3DMark Vantage is the new industry standard PC gaming performance benchmark from Futuremark, newly designed for Windows Vista and DirectX10. It includes two new graphics tests, two new CPU tests, several new feature tests, and support for the latest hardware. 3DMark Vantage is based on a completely new rendering engine, developed specifically to take full advantage of DirectX10, the new graphics API from Microsoft.
The Extreme settings were used for testing, so a resolution of 1920×1200 was used.
In the overall score we see a very marginal difference between the XFX Radeon HD 4890 and the Sapphire 4890. When compared to the 4870 1GB, we see some separation.
The GPU score gives you a slightly clearer picture of how much the GPU affects the total score. The pair of 4890s clearly runs away from both the 4850 and 4870.
