Intel Core i7 920 Nehalem 2.66GHz Processor Review

Intel Core i7 920 Nehalem 2.66GHz Processor Review - PCSTATS
Abstract: If you're a computer enthusiast, you're likely already familiar with Intel's Core i7 processors, which have been widely hailed as the fastest desktop processors available on the market today. Introduced at the end of 2008, Intel's newest desktop processors are finally maturing and becoming more accessible in the market. It's time to take a look a fresh look at the Core i7 processor.

32-Bit 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.

In physical and scientific simulations, we see the Intel Core i7 920 trading blows with AMD's processors. Since this test only takes advantage of two of the available cores of the Intel Core i7 920, this test won't show the processor's true potential.

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 loves memory bandwidth, big caches and multiple cores, so it's not really a suprise who the winner is here.
