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

Par2 is healthily threaded so the Athlon II X4s continue to do well here. The Q8200 inches by the 620, but for all intents and purposes it's the same speed as the $99 fighter from AMD.

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:

The roles are reversed here, and all of the AMD architectures prove faster than their similarly priced Intel alternatives.

    This losing battle for AMD has been going on since the introduction of the Core 2 Duo years ago. Where have you been?
  • mdk77777 - Wednesday, September 16, 2009 - link

    945 has been at $170 for weeks. That's a $55 difference from the price listed by ANAND :!: , it is also available at 95 watt :!:
    955 has been at or below $200

    But that would conflict with the second coming of I5 at $210 so he conveniently ignores current pricing. :mrgreen:

    Talk about bias, you write an article about pricing and market position and then ignore current pricing and market positions.

    Pretty amazing.

    You do understand what the listed prices are, and just want to flame, right?
  • mdk77777 - Wednesday, September 16, 2009 - link

    How does AMD respond to Lynnfield? Is it by drastically cutting prices on Phenom II? Nope.

    Thats how the article starts. Correct, but they lowered prices weeks ago in anticipation.

    A list price means nothing if it has been widely, significantly, and uniformly discounted.

    Obviously they will update. Again, a story about market prices and market value of various CPU should reflect the market pricing.

    you are correct that the actual prices are what matters -- after all, the entire point of this (and most if not all) article(s) here are for the benefit of people considering a purchase.

    And then they talk about anand not being biased...

    PII 955 $189
    PII 945 $169

    Hey even in my country (Peru) wich has a lot of tech taxes the 955 costs less than AMD "official" price.

    Depending on which sites someone uses, they may not offer a better deal than another site they may be unaware of, likewise they could get a CPU for cheaper than you or I can. It's strictly relative in the end and doubtful to be the result of some sort of bias. Anand seems very impressed with the Propus and so too will be a lot of other people.

    Looking more closely at it, I believe it should perform closely with a similarly clocked (or overclocked?) Phenom I due to the lack of an L3 cache, though I couldn't say which would perform faster. Incidentally, I've been checking dabs.com and their most popular CPU is the Phenom X4 9650 at about £80; this is only 2.3GHz and is more expensive than the newly-launched Athlon II X4 620 by about £5, so it stands to reason that people will go for this one instead soon enough.

    What I would really like to see, however, is a direct comparison between the 620 and the PII X4 905e (2.5GHz, 6MB L3) - it should be relatively simple to overclock one/downclock the other and see how much the lack of an L3 cache hurts the Athlon in a head-to-head, why the Athlon II X4's TDP is 95W whereas the 905e (with the 6MB L3 cache, remember) has a TDP of 65W, and whether it's worth the extra £50 for the 905e.

    I did look at other CPU prices on this site as well as on a couple of others. The PII X4 955 and the i5-750 are roughly the same at about £150-£155 (though dabs.com has the 955 as £165 for some daft reason), whereas the PII X4 965 is closer to £180. It's very important to look around for the best price, however I'm starting to doubt the reason for the 965's existence now, at least until they cut its price.

    Indeed, shopping around is essential, and watchout for shipping
    charges aswell.

    After deciding what to buy, I Google for the part numbers or names
    of the items I want, gather a selection of sites, see what can be
    saved re shipping costs by buying multiple items from one seller.
    I've ended up using a variety of companies over the years, sometimes
    well known (Dabs, Scan, Microdirect), sometimes more obscure (Komplett,
    C&C Central, Lambdatek, Overclockers, Tekheads). And doing it this
    way means one has a better chance of locating special offers. I also
    check on eBay for BIN offers from reputable sellers, which in one
    case resulted in the best price for a PSU I wanted. The company names
    above are in the UK, but the same applies anywhere.

    1. A benchmark should test the architecture clock for clock. Dynamic overclocking just messes things up even if it's on by default.

    Sure Turbo is a nice addition and sure it should have been available ever since dual core CPUs appeared just to prove customers that you're doing something about single thread performance too.

    Turbo is a feature, not an architectural advantage. It's like saying a mainboard with Quad GigabutLAN on P45 is more performant than a Dual LAN on X58 just because it has this feature of having four LAN ports. Sure, if you do a LAN performance test you could find many ways in which you could show that the mainboard with Quad LAN is faster but surely you couldn't argue that P45 is superior to X58.

    Anyway ... the testing shoul have been done with Turbo on and Turbo off to clearly show thr difference .

    2.Deneb is 252% of Propus (300mln -> 758 transistors) but only offers around 10% performance improvement... Could you justify making the die size so much bigger just for 10%? Besides, if we talk about profit, if 252% = 225$ (Phenom 3GHz) and 100% = 99$ (Athlon II X4) ... Propus seems more profitable .
