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.

    "For example, today the fastest LGA-1156 processor is the Core i7 880. When Sandy Bridge launches early next year, the fastest LGA-1155 processor will be the Core i7 2600."

    Shouldn't the second one also read LGA-1156? Are they changing the pin count/socket for this 'tock'?

    Well, that's me being an idiot and not reading the whole article first... New socket indeed. Reply

    So intel has locked multtipliers because of some other evil companies, eh? To protect the consumers, right?

    What a shame... :(

    The story of how caches are going to work in the 8+ core world is getting exciting. I like the overview at the daily circuit that summarizes how Niagara 3, Tilera Gx-100, and BlueGene/P processors weigh in on the issue too

    The Apple iMac 21.5inch is a computer machine which uses the power of Intel Core i5-2400. Look at these page: http://www.bestdealscomputers.net/desktops/new-app... Processors like that, thanks to its strength, could draw the attention of everyone, even computer vendors at the level Apple also has without a doubt to hook them. Reply

    It's hard to wade through all this data so quickly. That said, as far as overclocking, the new 2011 socket will be the successor to 1366 ?

    I hope with all these new overclocking controls there will still be that mainstay $300 CPU that can overclock to some extreme performance. Meaning a successor to the i7 920/930 that can deliver the amazing performance those can overclocked.

    I hope this is not the death knell for such a CPU and Intel is expecting us to fork over $1000 for that performance level.

    Good question, but judging by the road map, the Extreme and Performance segments are still Gulftown Processors. I think the 1366 stays for Gulftown. Reply

    On the 2P Server side of things, I have been told there will be a Westmere v2 coming in January 2011.
    This is probably the same family that will produce the i7 990 and the other 1366 chips on the chart that don't exist yet. The Xeon 5600 and 970/980 are damn near identical aside from QPI Links.

    Being those are being released in Jan, I wouldn't expect to see a socket 2011 desktop part until basically a year from now.

    They will once again be a close relative to the 2P Server family. The socket for the 2P Servers will be Socket R and will be Quad Channel memory as well as supposedly having PCIe 3.0.
