Cinebench 3D Rendering
To further illustrate the point we've made relative to the test system being GPU-limited, we also ran Cinebench which is a 3D Rendering benchmark based on Maxon's professional-grade Cinema 4D rendering software.
The Cinebench 2003 benchmark is an OpenGL 3D rendering performance test, based on the commercially available Cinema 4D software suite. This is a multi-threaded, multi-processor aware benchmark that renders a single 3D image 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).
Our Cinebench results show us what the Core 2 Duo T7600 is capable of, if it were not held back by the Mobility Radeon X1600 is our test system. In both multithreaded and single-threaded test runs the Core 2 Duo T7600 Merom processors is 25%+ faster than the fastest Core Duo T2600 chip and 48-50% faster than the 1.83GHz Core Duo T2400. This is easily the largest performance advantage we've seen in our testing here with Merom and perhaps a hint of the potential for additional headroom in the future for Mobile Core 2 Duo as third-party software is continually optimized for the architecture.
On a side note, just for reference, a similarly equipped Athlon 64 FX-62 dual core processor based system scores about the same as our Core 2 Duo T7600 posted here. That's a full-power 2.8GHz dual-core desktop chip versus a 2.33GHz notebook CPU -- impressive to say the least.
