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.
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:
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.
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.
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 Clarkdale lineup is honestly made up of CPUs that are too expensive. The Core i5 670, 661/660 and 650 are all priced above $170 and aren’t worth the money. The problem is Lynnfield’s turbo mode gives you high enough clock speeds with two threads that there’s no need to consider a dual-core processor. You can buy a Core i5 750, have more cores than any of these Clarkdales and run at close enough to the same frequencies for $196."But then you have to pay extra for a discrete graphic card and not every application need the extra graphic power!

Wow, I was going to write about how you wouldn't have to buy a discrete graphics card if you went with a Core i5 750 because you could just choose a motherboard with an integrated graphics chip. But then I checked online and it seems that there aren't any P55-based boards with integrated graphics - wow! Wouldn't have believed it myself.However, Anand's point still stands when comparing the Clarkdale i5's to the Phenom II X4, for which you can get many boards with integrated graphics.

"when comparing the Clarkdale i5's to the Phenom II X4, for which you can get many boards with integrated graphics"...but Clarkdale already has integrated graphics.

It's because P55 is a southbridge, not a northbridge.Taft12 - Monday, January 4, 2010 - link
But then you have to pay extra for a discrete graphic card and not every application need the extra graphic power!Only if you don't already have any PCI-E x16 card. Is that true for a single reader of this site? And truly ANY PCI-E card will perform better than Intel's on-chip solution, even one 3 generations old.

so the price goes up another $30-$40. As to your question of truth, yes I spend 40 hours a week on an intel IGP dual core as it is, so do the other 1000 people in this building doing engineering work that's processor demanding but graphics independent.nubie - Monday, January 4, 2010 - link
There are rafts of HP 8400 OEM pci-e cards on ebay right now for $15 (total, no shipping or tax), that should even accelerate your Flash 10.1 and video just fine.If you even need it that is, and it is clear that for many there is absolutely no use for more than the integrated graphics.

Hi Anand. Looks to me like something weird is up with your Everest benchmarks. Shouldn't the 24X multiplier have the faster scores?-Patrick

Hi Patrick,Fixed it, the images were reversed.
Thanks!

Good Article Anand. I'm going to be building my first HTPC soon, but I want to be able to do some light gaming on it, and it doesn't look like the integrated graphics have come far enough yet. If the 661 was priced lower I would consider it, but for nearly the price of a 750 you are right in saying it makes no sense. 750 + 5750 discrete graphics for me please :)Will someone be posting an updated system buyers' guide soon?
