CINEBENCH 2003	Source: Cinebench

CINEBENCH 2003 is the free benchmarking tool for Windows and Mac OS based on the powerful 3D software CINEMA 4D RX. The tool is set to deliver accurate benchmarks by testing not only a computer's raw processing speed but also all other areas that affect system performance such as OpenGL, multi threading, and multiprocessors.

Cinebench 2003 is an interesting benchmark, the CPU portion of the test certainly gets a fair performance boost when running as a true 64-bit application but its 3D rendering capabilities are lower. This illustrates a good point, while there are 64 bit applications on the market, many are buggy and support can be inconsistent.

Mol Dyn: Molecular Dynamics is a method for simulating the thermodynamic behaviour of materials using their forces, velocities, and positions. Most important of the afore mentioned is the force. Primordia: This code calculates the Quantum Mechanical Hartree-Fock Orbital for each electron in any element of the periodic table Lower times indicate better results.

The 32-bit version of ScienceMark 2.0 runs at the same speed in both 32-bit and 64-bit OS's. The program greatly benefits from a pure 64-bit computing environment and processor.
