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.

WinRAR - Archive Creation

Our WinRAR test simply takes 300MB of files and compresses them into a single RAR archive using the application's default settings. We're not doing anything exotic here, just looking at the impact of CPU performance on creating an archive:

    It's funny, AMD will never get any profit and still loss after 3 years consecutively. I belive you can not buy any AMD product when Intel roll out the Larrabee. I believe Intel will win in this market too and will crush NVIDIA like AMD before. Intel will own all and everyone will be happy both customers and the consumer.

    You missed Econ101.

    I *know* that you are clueless.

    Yeah well they had to absorb 5 million to buy ATI.
    So everyone would be happy if Intel owned everything huh? Would anyone here be happy paying $1000+ for a cpu? I think not. You are clueless. AMD will return to profitability next year and will completely own the GPU market by then. Without AMD, no Intel fanboy would be happy period.

    No offense, but you don't know what you are talking about! AMD currently owns 31.5% of the CPU market to Intel's 68.5%. That's better than a 5% increase in the last year alone! Rumors have it that nVidia is canceling some of it's higher end video cards because they can't compete with Ati in the high end market, so Ati's market will grow even more, which means even more profits for AMD!

    The article also claims that nVidia may even abandon the high end cards altogether!

    Intel is in the awkward position of having the best computer, but almost no one can afford it, so the original i7 is relegated to the server market. They also have to maintain production of faster CPUs than AMD makes! AMD has two low priced Quad cores, the Athlon IIx4 620 and 630. $99 and $122 respectively. The 620 will overclock about 800MHz, while the 630, over 1GHz, both on air! From a price/performance point of view, AMD wins hands down! AMD has invested heavily in the low to mid price market, and have a wide variety of CPUs to cover any need. I would say they have planned well, and should be in a very good sales position during the continuing recession!

    I would also like to point out that AMD hasn't made a major mistake in well over a year. Products have come out when they were supposed to, and there haven't been any real glitches in any of the new CPUs. They've also continued to refine these new CPUs to the point that the Phenom IIx4 Deneb 940 overclocks better and is a better all around CPU today, than it was when it was first introduced!

    And for the best business deal of the new century, hands down! AMD sold their entire multi-billion dollar debt by selling their Chip Fabs, while still maintaining operation and control of them! I don't think these guys are about to fold their tent quite yet! I believe they are a lot smarter than you think!

    This is FUD, currently Intel owns 80 something percent marketshare as opposed to AMD's 11.5%. Were discussing CPU's not GPUs.
    http://www.eweek.com/c/a/Desktops-and-Notebooks/In...">http://www.eweek.com/c/a/Desktops-and-N...e-Lead-O...

    Discrete and Integrated GPU marketshare is seperate, there are 3 competitors there, Intel, AMD/ATi, nVidia.

    Overclocking is only relevant to the budget enthusiast and that represents a small section of the market. What matters is stock performance not overclocking.

    AMD wins price/performance, but they lose on brand image, and that is more important as that allows Intel to sell processors at the same performance for a higher premium and garner more profits.

    It's about time that AMD hasn't tripped on it's 2 feet, as if they had continued to do so, Intel wouldn't see them as worthy of making any price adjustments over.

    No AMD will not be going anywhere soon, we still need them, we all need AMD to continue to exist for different reasons.

    I hope you were joking about satisfied customers. Intel will again simply "own" its customers, as it did years before, when it felt no competition.

    Larrabee is a big unknown. I suspect it won't be as good as anybody hopes and initially drivers will suck. My guess is larrabee version 2 will be much better but probably still suck compared to equivalent amd/nvidia, and maybe version 3 (in like 5 years) will be competitive. And that's if intel doesn't just give up again like they have every other time they say they will make good graphics. The barrier to entry into the graphics market is huge now, it's not simple to design a dx11 gpu core that works (just ask nvidia) let alone one that is fast. And then drivers are a constant work in progress. I don't believe a new player can come along and get it all right their first try.

    That's why Intel actually does not imply they are making a GPU but rather a processor with GPU capabilities. Interestingly enough NVIDIA also backs off the notion GPU. I guess the only pure next generation GPUs will be ATI. What is going to come after that - nobody like us knows yet.
  • rhorwitz - Tuesday, October 20, 2009 - link

    Oh you are so terribly mistaken! Without any competition Intel would raise its prices so high that only the rich could afford a PC. If it were not for AMD (or any other competitor) we would still be using first generation pentiums costing $500 ea. To make an assinine statement that "...everyone will be happy both customers and the consumer." is pure unmitigated BS.
