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.

Lower calculation times are better.

In physical and scientific simulations, we see the AMD Athlon II X4 635 processor trading blows with Intel's processors. Since this test only takes advantage of half of the available cores of the Athlon II X4, this test won't show the processor's true potential.

Performance in Windows 7 is about the same as Vista.

WinRAR Internal Benchmark	Source: RARLabs

This command generates random data, which contain specially introduced redundancy increasing load to processor and memory. Then data are passed through RAR compression and decompression algorithms and output of decompression algorithm is compared with source data. If any difference found, WinRAR reports "Errors found - Yes" in the command window. Also WinRAR displays a size of processed data and compression speed, current and resulting, in kilobytes per second. You may use the resulting speed value to compare RAR performance in different conditions.

Higher results are better.

WinRAR's also does well with quad-core processors, so while it's ons of the slowest quad-cores, the Athlon II X4 635 is still faster than any of the dual or triple-core processors in this test.

Not a huge performance change here, even with the change in operating system.
