3DMark05 is best suited for the latest generation of DirectX9.0 graphics cards. It is the first benchmark to require a DirectX9.0 compliant hardware with support for Pixel Shaders 2.0 or higher! By combining high quality 3D tests, CPU tests, feature tests, image quality tools, and much more, 3DMark05 is a premium benchmark for evaluating the latest generation of gaming hardware. Prime95 was running in the background to simulate load on a one core.

Multi-threaded tests mean the benchmark is taking advantage of one core while Prime95 is being tasked to the second, so in effect both cores of the dual core processors in this reference list are being taxed. Looking at the overall score for 3DMark05 we aren't seeing much of a change between each CPU model. The CPU portion of this test takes a big hit under multi-threaded loads. The Intel Pentium D 940 does not suffer as much as the Pentium D 840 does when one core is running under a Prime95 load.
