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.

    This CPU is a joke until it's getting sold for under four hundred dollars....

    Why just not take i5-750 and overclock the heck out of it and beat the "crab" out of the i7-970?

    Does overclocking net you additional cores now?

    (Sarcasm aside, you CAN net additional cores on an AMD CPU!)

    Cause then you can overlock the i7-970 and beat the "crab" out of anything else, minus the 980X.

    Which still won't justify 5 times higher price.

    Never said it did. I can't see why anyone would ever pay $500 or more for a processor you'll be using at home. I'd say it's a different story if it's a work related business expense.

    Me, I will never buy a proc that costs more than $350. I always stay within that budget. I find that the sweet spot. You can get a fast processor and you can usually overclock it to match the $1000 ones.

    Intel's pricing strategy seems to pay off in the end, historically. :)

    It's pricey but very quick at pretty much everything.
    Thanks for the look anyway.
    Could AT consider an article highlighting the need for software that really shines on this hardware?
    Who's coding 6 core +HT stuff anyway?
    Give them a push Anand :)

    "If you're doing a lot of 3D rendering, video encoding or other heavily threaded tasks it makes sense. Otherwise, despite the class leading performance, it's not a good value. "

    Read the review!!! .... damn it
