3DMark05 CPU Test

 

We've included Futuremark's 3DMark05 in our testing suite for CPUs only at this point in time.  The CPU tests of this benchmark were the only subroutines we enabled for our test run.  Additionally, we've taken a snippet from a section of the Futuremark 3DMark05 white paper that explains exactly what the CPU test does specifically.

As in the previous 3DMark version, the CPU test runs game tests in low resolution using software vertex processing and disabled post-processing. This decreases the graphics card workload, and makes the test result reflect above all the CPU's performance rendering 3D scenes and performing other 3D game related tasks like performing matrix calculations. The CPU test also uses fixed frame rendering to further ensure the workload stays the same for all systems.

In 3DMark05, an additional workload typical for the CPU in 3D games has been added. The CPU not only calculates the vertex shaders; it also continuously calculates the flight path of the air ship. The air ship actually flies the same path every time, in order to keep the workload the same between different systems, but the calculations are performed as if it would intelligently steer according to the canyon shape and other obstacles like the sea monster jumping up from the water. The path finding algorithm used is D*Lite (http://www.cc.gatech.edu/fac/Sven.Koenig/).

For the Pentium 4 lineup in this test, it looks like overall clock speed dictates the results.  However, this is definitely not the case for the AMD Athlon scores, where a 2.6GHz Athlon FX-55 beats out the 3.6GHz Pentium 4 560 Prescott core CPU.  That's a full 1GHz differential in clock speed, and AMD's flaghship desktop core still wins by a small margin.  The new 3.46GHz Extreme Edition P4 drops in about where we expected in this benchmark with a slight edge over the standard 3.4GHz P4 EE.
