Futuremark 3DMark Vantage

Futuremark's synthetic 3D gaming benchmark, 3DMark Vantage, uses some advanced visual technologies that are only available with DirectX 10. 3DMark Vantage isn't simply a port of 3DMark06 to DirectX 10 though. With this latest version of the benchmark, Futuremark has incorporated two new graphics tests, two new CPU tests, several new feature tests, in addition to support for the latest PC hardware. We tested the systems here with 3DMark Vantage's Extreme preset option, which uses a resolution of 1,920x1,200 (as this exceeded the native screen resolution of the Core i7-920XM whitebook, we conducted this test with the notebook sending its video out to an external display).

Even though the Core i7-920XM has what is arguably the fastest mobile CPU and mobile GPU (the Nvidia GeForce GTX 280M) available today, we still wouldn't expect this amped-up mobile platform to beat high-end desktop gaming rigs when it comes to 3D graphics. We ran this test primarily to see how close the platform could come to desktop-like 3D graphics performance. We'll be the first to admit that the Core i7-920XM whitebook's 3D graphics performance wouldn't make it a candidate as our first-choice system for a LAN party, but its gaming performance is about some of the most-powerful we've seen for a non-SLI notebook.

3DMark Vantage's CPU Test 2 is a multi-threaded test designed for comparing relative game physics processing performance between systems. This test consists of a single scene that features an air race of sorts, with a complex configuration of gates. There are aircraft in the test that trail smoke and collide with various cloth and soft-body obstacles, each other, and the ground. The smoke spreads, and reacts to the planes as they pass through it as well and all of this is calculated on the host CPU. We disabled the benchmark's Nvidia PhysX in order to better isolate the performance of the CPU.



The Core i7-920XM whitebook handily beat the 2.8GHz Core 2 Duo X9800-based Dell notebook, as well as holding its own against the 2.66GHz Core i5-750 and 2.66GHz Core 2 Quad Q9400 systems. Not surprisingly, the most powerful system on this test uses the highest-end desktop processor of our comparison systems, the Core i7-920 desktop CPU.
