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.

    I will be buying one of these the day it comes out.

    The only question will be between whether I get a CoreI5 or the Corei7. It will depend on price I guess, as the max I am willing to spend on a i7 CPU is $250.

    Anyways, should be a nice upgrade to my E8400.

    Considering how great of a quad core the Core i5-750 is at $195, hopefully they'll have some great quad cores at about $200.

    I've often wondered why people don't use WoW to test their video performance in the computers they are testing, and the obvious occurred to me - it so much depends on where you are and what the population is in the area you are in, that the frame rates vary widely. I imagine the frame rates reported here were for an area like Durotar with no one else in sight, heh. It would be a good place in terms of consistency, anyway, though less taxing that somewhere in Storm Peaks.

    WoW is often described as a CPU-intensive game, and so a great game to be included in tests of CPUs like you are doing here. Thanks for including it! I hope it is used for more video card tests as well; WoW may not be the most taxing test bed at lower end video, but at upper end in some areas it can hit 4 GHz i7 based Crossfired systems hard. I like playing at 85 Hz everywhere in the WoW universe I go - and Cataclysm will bring new video challenges, I'm sure.

    I'm a bit disappointed at Intel's attempt to completely lock us out of over clocking all together. But maybe this is AMD's chance to win back the enthusiast market. If AMD sold only unlocked parts, they would have a market segment all to themselves...

    OK, didn't see it in the article and don't really feel like wading through 200 comments. What I want to know is will we be able to either A) disable the onboard graphics if we have the latest and greatest bad-ass video card...or even better, B) Will it be able to run both at the same time in a configuration where when I'm doing just generic web surfing, emailing, etc, the Intel GPU is doing the work and the discrete card can power down (quieter and less heat generated), and then when I fire up a game, the discrete powers up and the onboard powers down?

    Intel is screwing over minorities! Colorblind people unite!

    "Both H67 and P67 support 6Gbps SATA, however only on two ports. The remaining 4 SATA ports are 3Gbps. Motherboard manufacturers will color the 6Gbps ports differently to differentiate."

    Higher performance integrated GPU's should help bring some of the gaming market back to the PC. That is a very good thing. :)

    I'm sorry anand but is this because your intel frendly?

    Come on..you have to run high resolution(2560x1600 or higher eyefinity) gaming benchmark too.

    Sandbridge is nothing if it doesnt have much supiror performance in high resolution gamming.

    But I know intel sucks. Even 980X is sometimes sucks in high resolution gaming.

    When I see your bench, I can clearly SEE your intel frendly. Espesilly in gaming part.

    Anand, of course your site is very popular(even in my country korea).

    But in reality..your nothing but a intel suckass indian.

    Stop. You're making yourself look like a bigoted fool.

    Naaah, you're not a Korean. Only Americans make dumb spelling mistakes like "your" in place of "you're".
