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

Our Par2 test gets a nice boost from more cores, making the i5 661 overpriced in this case. The i3s however do very well, outperforming the Athlon II X4 630 and the triple-core Athlon II 435.

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:

WinRAR 3.8 Compression - 300MB Archive

The lighter the desktop workload (as in the fewer stressful threads you have running) the better Clarkdale does. The Core i3s are particularly sensible here. It's basically Intel's answer to the Athlon II X4 600 series.

Microsoft Excel 2007

Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.

Intel believes that one of the biggest cases for Clarkdale in the business market is Excel performance. The Core i5 661 continues to be overpriced for what it is, but the i3 540 and 530 look very good here. They're can outperform the Athlon II X4 630 and draw less power. Nice.

Sony Vegas Pro 8: Blu-ray Disc Creation

Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spend encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.

Sony Vegas Pro 8 - Blu-ray Disc Image Creation (25Mbps MPEG-2)

The i3s come pretty close to doing well in our Blu-ray creation test, but once again the i5 661 falls short thanks to its ridiculous price. The i3s are a reasonable alternative to the Athlon II X4 630.

Sorenson Squeeze: FLV Creation

Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.

Sorenson Squeeze Pro 5 - Flash Video Creation

Clarkdale isn't a good choice for this test, with the 661 matching the Athlon II X4 630. The i3 parts place below AMD quad-cores but above the tri-core offerings.

    The Intel G9650 doesn't exist, what You're referring is Intel G6950

    I've been building systems since the late 90's, mostly for others, and I'm always the last to get a decent system so I decided it was about time for me. I'm running an e6600 on a 3 yr old Intel board w/ 2g of DDR2 RAM and was wondering about the differences between C 2 quad, i3-540, i5-750 or i7-820. I priced out 3 different setups with Gigabyte boards (EP45, H57 & P55 - USB3 ver.) combined with Q8400/9300/9400 on EP45, i3-540,i5-750 and i7-820 on the H57 & P55 and 4 Gb DDR3 RAM (Crucial, Geil, Kingston)so , basically, I had 9 combinations. Excluding the i7, the price range for these builds was about $429 - $487, and I could probably do better if I tried but I was amazed that they were that close (the i7 adds another $100 but not that much improvement in performance that I can see).

    Looking at your charts, I think I can justify going with the i5-750. I have a decent video card for the occassional gaming that works pretty good for me now (I'll apply the $100 from above to a better card later) but I do a lot of spreadsheets and some photoshop and autocad so I think I'll see a better improvement there.

    Thanks again for all your articles. Very well written, understandable and thorough.

    I too am puzzled by the i7 870 scoring so low on the World of Warcraft chart -- it stood out to me immediately when I first read the article. I was a little surprised to not see it mentioned.

    It was suggested in another comment that this was due to the game having an issue with hyperthreading, but if that was the case shouldn't the i7 920 also have scored significantly lower than it did?

    It should be noted that this new intel system does not work
    at 1080p/24 correct. The nvidia 9400 chipset works at 1080p/24.
    So i've traded audio for skipping.
    HTPC is no better off. Sad.

    Previous Intel IGPs managed achieve less terrible numbers in game by cheating- they didn't render all the polygons and textures. So for good measure i require side by side screenshots of the "new, better, faster and cheaper" Intel IGP.

    The idea of an Intel IGP that simply isn't horrible is SOO strange that a true review would have to go the race: benchmarks, screenshots, minimum playable settings for various games and screenshots. Something the articles on HardOCP.

    Why isn't the i7-860 tested in the section "Windows 7 Application Performance"?

    Without the i7-860 in the Windows 7 test section, this review is pointless.

    I was hoping to build a new always-on home server around one of these. Power miserly IGP and idle operation (for when it's only firewalling and routing) but plenty of grunt in reserve for occasional video encoding, compiling and running virtual machines.

    Looks like they missed the mark for this application, and I couldn't even adopt now and wait for the real deal CPU later, as the socket is a dead end.

    IMHO only the HTPC crowd have a reason to be excited here, but there are lots of other (cheaper) ways to get low power 1080p too.

    Let's wait and see - There are products coming which will do gpu assisted transcoding that might shift things in Clarkdale's favor. Reply

    I know for a fact that the athlon II x3s and x4s have to overclock like crazy in games to reach the same performance delta as their phenom II x3 and x4 brethren
    (coz of the 6mb cache and many games are dependent on cache)
    Ive seen gaming benchmarks on anandtech where the x3 720 matched the x4 965 when they are both overclocked to 3.8ghz.
    I was able to buy an x3 720 for only a 110 usd recently.
    So why isnt it in the benchmark comparisons?
