AMD Athlon II X4 645 3.1GHz Socket AM3 Quad-Core Processor Review

AMD Athlon II X4 645 3.1GHz Socket AM3 Quad-Core Processor Review - PCSTATS
Abstract: In this review PCSTATS is testing AMD's latest mainstream quad-core chip, the 3.1GHz Athlon II X4 645 processor. Architecturally speaking the Athlon II X4 645 is identical to the preceding Athlon II X4 635 model, except for a modest clock speed increase.

CPU Calculation Benchmarks: ScienceMark2.3, WinRAR

ScienceMark 2.3 Source: ScienceMark

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.

ScienceMark illustrates how some benchmarks favour optimization, and the number of discreet cores over the number of threads a processor has. In the Primordia benchmark the quad-core Athlon II X4 645 weighs in with a result of 190, a few points ahead of its predecessor.

The Mol Dun benchmark posts slightly different results, with the quad-core Athlon II X4 645 processor having a result of 47, about the same as the dual-core Intel Core 2 Duo E 8400 CPU.

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.
