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.

Clock for clock there's very little advantage compared to Lynnfield, but compared to the i7 760 the Sandy Bridge advantage is no less than 35%.

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:

Without Hyper Threading, the Core i5 2400 equals the performance of the Core i7 880. Turn HT on, and this Sandy Bridge part that may end up costing ~$200 is nearly as fast as the $999 Core i7 980X.

    And why didn't you ran 2560x1600(or higher resolution like eyefinity) benchmark either?

    Is this because sandybrige is not that good?

    So you're expecting eyeinfinity out of a single integrated graphics connection out the back of a motherboard?

    Are you okay?

    i7-950 vs i7-2500K... So which will be faster and a better gaming chip? anyone?

    Fantastic preview! I am definetly getting sandy bridge now. Apparently the Gigabyte P67-UD7 will have a geforce n200 chipset and support full 16X/16X sli AND crossfire! It will make a significant upgrade from my Phenom 2 and I cannot see myself waiting for bulldozer which has apparently been delayed (gee what a surprise!) until Q4 2011.

    which sample did you use for your tests?

    QDF Q12W = GT1 (850-1100MHz)
    QDF Q12X = GT2 (850-1100MHz)

    Hey guys, checkout this review of the i7-2600k... I think its bogus...tell me what you think of it on here.

    Catalyst 8.12... WTF! 2 year old drivers? How much did intel bribe you to use drivers that old for their competition? That is a really bad path to guy down... Tom's did weird stuff like that a while back and lost readers because of it.... You just lost my respect Anand....

    I don't think an entire product line of CPU's with on-board graphics is anything really to get excited about, especially for us geeks. I guess I'm just old-school. The Sandy Bridge ,like Clarksdale, has similar benefits from a single-chip chipset which is very appealing from a throughput and control standpoint.

    Take nother look at Sandy bridge

    Wow Intel owns when it came to converting video, beating out much faster dedicated solutions, which was strange but still awesome.

    I don't know how AMD's going to fare but i hope their new architecture will at least compete with these CPU's, because for a few years now AMD has been at least a generation worth of speed behind Intel.

    Also Intel's IGP's are finally gaining some ground in the games department.
