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.

Science mark usually does quite well in the Primordia dual-core benchmark, but in this case the AMD Phenom II X3 720 Black Edition processor is still quite a bit slower than the Core 2 Duo processors. Things get worse in the Mol Dyn benchmark, where even the slowest Intel processor can beat AMD's entire line up of Athlon and Phenom processors.

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.

Extra cores are also very useful in WinRAR, and with an extra core the AMD Phenom II X3 720 Black Edition is able to take an easy lead over its dual-core rivals in this test.
