Intel i925X and i915G Architecture, Pentium 4 560 and 3.4GHz EE - The LGA775 Debut
Cinebench and Lame MP3
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). We ran two sets of numbers, one in single-thread mode, and another in the benchmark's multi-thread mode for our HyperThreading enabled P4 test systems. The Athlons are only capable of running the single thread test, hence their lack of those data points in the graph below.
Prescott's deep pipeline seems to be standing in the way for Intel in this test as the 3.6GHz P4 560 puts up the second slowest score in the graph. AMD's Athlon 64s put up a strong fight on the other hand and come very close to catching our fastest system config, which was the P4 EE 3.4GHz/i875 setup. Low latency and over all memory bandwidth are what put up good scores with Cinema 4D. Intel's Hyperthreading technology is also able to show its muscle as well in this application, since it can render 2 halves of the scene simultaneously
Lame MP3 is new to our test suite here but we thought it was an important component to include as a performance metric. Converting audio files to MP3 format is a very popular scenario that many end users work with on a regular basis, to provide portability and storage of their digital audio content. In this test, we chose a large 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format. Processing times are recorded below and shorter times equate to better performance.
Clock speed again provides the edge to Intel here once again for the Pentium 4, although it is a very close match-up over all. However, Prescott's deeper pipeline once again proves to be a bit of a hurdle, with even the 3.6GHz P 560 losing out by a small percentage to the 3.4GHz Northwood system. It's also interesting to see how the P4 EE's large 2MB L3 cache doesn't help much and this benchmark posts identical scores for both Gallatin and Northwood core based CPUs.
