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.

This is where things get interesting. In UMA mode the performance is the worst of all as the system memory is running the IGPs frame buffer. In SidePort mode and SidePort+UMA the systems perform almost identically. There is a slight increase in performace with SidePort+UMA, but not by a lot. This could be offset by the performance hit the system takes for using the system memory as VGA memory over the advantages of having beyond 128MB of graphics memory.

However, the constant here is that the 785G's DX10.1 graphics system is slightly better than the older 790GX.
