3DMark05 CPU Test
It may not be an actual game, but 3DMark05's built-in CPU test is a DirectX-based game engine metric that's useful for comparing relative performance among similarly equipped systems. This test consists of two different 3D scenes that are generated with a software renderer, which is very much dependant on the host CPU's performance. This means that the processing loads normally reserved for your 3D accelerator are instead sent to the host processor. The number of frames generated per second in each test are used to determine the final score.
3DMark05 is another benchmark with parts that are multi-threaded and take advantage of either Hyper-Threading, Multi-CPU-based systems, or dual core CPUs. We've always seen the Pentium 4 shine in this test. However, with the introduction of the Athlon 64 X2 4800+, AMD currently holds the lead spot, followed closely by Intel's Pentium Extreme Edition 840 CPU. From there things scale back to the Hyper-Threading-capable Pentium 4s, with the test leaning more in the favor of the extra memory bandwidth offered by the 1066MHz FSB-driven P4 Extreme Edition at 3.73GHz.
