SYSMark 2007 Performance
Our journey starts with SYSMark 2007, the only all-encompassing performance suite in our review today. The idea here is simple: one benchmark to indicate the overall performance of your machine.
SYSMark performance is a strong point of the new Clarkdale family. The Core i5 661 is able to deliver overall performance roughly equivalent to the Core i7 860. If you aren't running heavily threaded code that can really stress all four cores of a Lynnfield or Phenom II, the Core i5 661 is going to perform very similarly.
The real winners however are the simulated Core i3 540 and 530. You give up Turbo Boost but you still maintain Hyper Threading, which delivers Phenom II X4 965 performance for $133. Obviously AMD will still win in most tasks that stress all four cores, but for the majority of users you'll actually have roughly the same performance out of an i3 530. Impressive.
These Clarkdale chips are also a significant performance improvement over the older Core 2 based products. The i3 530 looks to be around 17% faster than the Conroe based Core 2 Duo E6750. Even AMD's value quad-core chips can't compete here, but that's just because we're not really stressing all four threads.

"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?
