PAR2 Multithreaded Archive Recovery Performance

Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive

Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.

Data Recovery - par2cmdline 0.4 Multithreaded

AMD's Phenom II has traditionally done quite well in our PAR2 recovery test, the 955 continues the tradition. It's the i7's Hyper Threading that gives it the significant edge here, but the Q9550 can't stand a chance.

Blender 2.48a

Blender is an open source 3D modeling application. Our benchmark here simply times how long it takes to render a character that comes with the application.

This is one of those unfortunate cases where switching platforms actually robbed us of performance, the 955 should outperform the 940 here but it put out numbers a bit slower than our older AM2+ platform which unfortunately doesn't have support for the new CPU just yet. Either way, the Q9550 is too far ahead to be toyed with.

Microsoft Excel 2007

Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.

In those scenarios where Intel has a distinct architectural or optimization advantage, the Phenom II doesn't stand a chance. That is unfortunately one downside AMD has to deal with. Intel's developer relations team is much larger and works much harder to ensure that more applications and workloads are optimized as best as possible for Intel CPUs.

    Cool. My next question would be to wonder why it didn't kick in for the other tests? I guess it wasn't enabled for them? Looks good overall.

    See page 4 - Turbo mode tends to activate pretty much any time a load is on the CPU. But it's not really "unfair" as all i7 users get that benefit without doing anything extra, plus i7 chips still overclock far beyond that point.

    Best post ever.

    Congratulations on the cryptic post... or is that pointless post? I'm guessing you're suggesting that the words listed were used with two different companies - AMD and Intel - but if so they certainly weren't used in this article in any way I can see. Care to enlighten the rest of us on the point of your comment?

    Some people are too clever for their own good; others merely think they're clever. Guess which one you are.

    Oh man, I thinking about the OC
    3.9GHz on Vista x64
    4.2GHz on Vista x86

    Why it happens?
    Does the results are the same using XP x86/x64 and Windows 7 x86/x64?

    That would be interesting to see if it is possible to reach 4.2GHz on Windows 7 x64

    Dont hold your breath. Theres more registers (etc) in use under a 64bit OS than a 32bit one. Its highly unlikely that there will be any difference on the exact same hardware. And even if there is a difference between xp/vista/7, 32bit 7 will outdo 64bit 7 as well. 64bit was never the ideal choice for overclocking records...

    In the CS4 test, given the large increase in performance when just going from DDR2 to DDR3, would a faster NB clock (2->2.6/2.8ghz) and faster than DDR1333 memory, while keeping the core at default clock, level the playing field with the core2 processors?

    Seems that in this particular test the phenom is starved for data.

    why do you use these 1GB dimm's in ddr3 config? I would assume you have more oc issues with 4 dimms in stead off 2 dimms?

    G.Skill DDR2-800 2 x 2GB (4-4-4-12)
    G.Skill DDR2-1066 2 x 2GB (5-5-5-15)
    Qimonda DDR3-1066 4 x 1GB (7-7-7-20)
    Corsair DDR3-1333 4 x 1GB (7-7-7-20)

    Nice article :-)

    btw... last paragraph on the first page... "faster than the Core 2 Duo Q9550." should say "faster than the Core 2 Quad Q9550."

    Intel and Amd are owned by the same person. Since a person can't have monoply in U.S. It has been divided into two different names and obviously diff. CEOs.

    cheers.
