Benchmark Tests

Benchmark tests were run with Altivec Fractal Carbon demo 1.2, CineBench 2003, and Xbench 1.1.3. I reboot between all tests (benchmarks and apps/game tests) to ensure as clean/consistent a cache/memory state as possible. Pure benchmarks are far less important than real-world applications tests, but many want to see them regardless. (The Apps tests page has results of tests with iMovie3, iTunes4 , MPEG4 movie conversion and Photoshop 7.0. The game tests page includes results with popular 3D games like Jedi II, Unreal Tournament 2003 and Quake3.)

Fractal FPU Benchmark:
I used the freeware Altivec Fractal (Carbon) demo v1.2 program (available here) to compare FPU performance of the original Dual G4/533 system and each of the upgrades. Test run in OS X 10.3.1 (not OS 9). Default settings were used. This is basically a FPU test (Altivec boosted and dual CPU aware). (Note: MegaFlops/sec = Millions of Floating Point Operations per Second.)

CineBench 2003 Results:
Since probably less than 1% of Mac users own Maxon's Cinema4D application, I use their freely available CineBench benchmark. (Which does more than just a simple timed render of a scene file - it also does shaded and wireframe model spins, "fly-throughs" of a 3D scene, etc. to show graphics card and cpu performance, not just rendering times.) CineBench 2003 is available at As with all tests in this review, the desktop was set to 1600x1200 model, millions colors.

I also recorded the FPS (frames per second) rate from the scene tests (these are not saved in the results normally). Here's a graph of the FPS rates from the 2 scenes in the Benchmark (results from OpenGL Hardware mode)
