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.

Since ScienceMark only uses two cores, the higher clock speeds of the Athlon II X3 435 serve it well when compared to the Athlon II X4 620. AMD processors tend do well in the Primordia test, but fall behind Intel in Mol Dyn.

In Windows 7, the Primordia results tend to be a little slower while the Mol Dyn tests are a little faster.

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 3.8 Internal Benchmark - Windows Vista KB/s Ranking Intel Core i7 920 3012 Intel Core i5 750 2433 Intel Core 2 Duo E8500 923 Intel Core 2 Duo E8400 1058 AMD Phenom II X4 965 Black Edition (140W) 1975 AMD Phenom II X4 955 Black Edition 1866 AMD Phenom II X3 720 Black Edition (DDR2) 1534 AMD Phenom II X3 720 Black Edition (DDR3) 1435 AMD Phenom II X2 550 Black Edition 970 AMD Athlon II X4 620 1348 AMD Athlon II X3 435 1230 AMD Athlon II X2 250 887 AMD Athlon II X2 240e 996

The Athlon II X3 435's doesn't do quite as well as the Athlon II 620 in WinRAR since it has one fewer core, but the additional 300MHz clockspeed still keeps this a close race.

WinRar's internal benchmark scores tend to fluctuate a lot between runs (due to the mechanical nature of hard drive caching), so don't read too much into the differences here between Windows 7 and Windows Vista scores.
