Using XBench and CineBench, it's apparent that MacBook's *are* in fact faster when using two DIMMs of the same size than using a single bigger DIMM. The configuration difference seems to have the biggest impact in graphics performance. Here's a link to the XBench comparison.

For reference, here's my PowerBook CineBench 9.5 results:

Processor        : 1,5Ghz PB G4 1,25GB RAM

MHz              : 1500

Number of CPUs   : 1

Operating System : 10.4.7



Graphics Card    : GeForce FX Go5200

Resolution       : 1024x768

Color Depth      : 24bit

Rendering (Single   CPU): 152 CB-CPU 

Rendering (Multiple CPU): --- CB-CPU 





Shading (CINEMA 4D)                : 161 CB-GFX 

Shading (OpenGL Software Lighting) : 485 CB-GFX 

Shading (OpenGL Hardware Lighting) : 1015 CB-GFX 



OpenGL Speedup: 6.32

Next we have the 1x1GB config 2.0 Ghz MacBook:

Processor        : MB 2GHz 1x1GB

MHz              : 2000

Number of CPUs   : 2

Operating System : 10.4.6



Graphics Card    : Intel GMA950

Resolution       : 1280x800

Color Depth      : 24bit
