Intel Pentium Extreme Edition 955 & 975X Express Chipset: 65nm is Here
Cinebench 2003 & 3DMark05: CPU
The Cinebench 2003 benchmark is an OpenGL 3D rendering performance test, based on the commercially available Cinema 4D application. This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The time it took each test system to render the entire scene is represented in the graph below (listed in seconds).
When running Cinebench 2003's single-CPU test, the Athlon 64 FX-57 and X2 4800+ outperform anything from the Intel camp by margins ranging from about six seconds, to as much as 28 seconds. Take advantage of Hyper-Threading and the second execution core though, and the Pentiums perform much better. In fact, in the multi-threaded test, the Pentium Extreme Edition 955 was the fastest of all the processors we tested, besting the Athlon 64 X2 4800+ by a half a second.
3DMark05's built-in CPU test is a multi-threaded "gaming related" DirectX metric that's useful for comparing relative performance between similarly equipped systems. This test consists of two different 3D scenes that are generated with a software renderer, which is dependant on the host CPU's performance. This means that the calculations normally reserved for your 3D accelerator are instead sent to the central processor. The number of frames generated per second in each test are used to determine the final score.
The CPU test built-into 3DMark05 is another multi-threaded test that shows the benefits of a dual-core processor. In this test, the Pentium Extreme Edition 955 posted the highest score of the bunch, nudging past the AMD Athlon 64 X2 4800+ by 180 points, or roughly 2.7%, and smoking both of the other Pentiums by margins of 678 and 1368.
