VapoChill XE II
While we had our Vapochill XE II assembled, we fired up a couple of applications and benchmarks to see what kind of performance we had gained by overclocking the system to over 4GHz. As you'll see, the 700MHz+, or 21%, boost in CPU clock speed definitely had an impact on overall system performance.

;) Stock Clock Speed 3.4GHz |
;) Maximum Stable Overclock 4.12GHz |
;) SiSoft SANDRA CPU/Arithmetic Benchmark Clock Speed - 3.4GHz |
;) SiSoft SANDRA CPU/Arithmetic Benchmark Clock Speed - 4.12GHz |
The CPU-Z screen shots above show our Pentium 4 Extreme Edition's specifics while running at its default speed of 3.4GHz, and overclocked to its peak stable clock speed of 4.128GHz. While our CPU was running at its default and overclocked speeds, we also ran the CPU Arithmetic Benchmark built-in SiSoft SADNRA 2005. As you can see, tacking on an additional 700MHz+ boosted raw performance by almost 18%.

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 configuration to render the entire scene is represented in the graph below (listed in seconds).
Performance in Cinebench was improved by 11.6 seconds by overclocking our processor to 4.12GHz. With our CPU clocked at its stock speed of 3.4GHz, it rendered the scene in 1 minute, 4.1 seconds, but while overclocked the process took less than a minute.
