ASUS Saves the Day: Simulated Core i3s
This is the board Intel sent for today's Clarkdale reviews:
It looks cool but it doesn't offer any overclocking features at all. You can't even adjust memory frequency or timings. It's like using a motherboard from ten years ago, just more stable.
The problem is Intel only sent us a Core i5 661 for review. A $196 Core i5 661. And we had no way of underclocking it to simulate a Core i3, the arguably more interesting CPU from today's launch.
I tried some of our P55 boards and had no luck underclocking the chips either. Apparently existing P55 boards need some BIOS help before we'll get that sort of functionality. Thankfully Raja had one of ASUS' boards in house for his upcoming H57 coverage - the P7H57DV-EVO. He confirmed that this board would let me disable turbo mode and decrease the clock multiplier on our i5 661. A FedEx shipment later and we're on track to providing an actually useful review.
ASUS' feature-filled H57 board
Today you'll see results from the Core i5 661 as well as a simulated Core i3 540 and Core i3 530. The GPU clocks are running at the 661's speed for these two simulated chips, but I didn't run any IGP tests with them so it doesn't matter. The uncore clocks are also possibly higher but I'm still waiting for Intel to confirm what the i3 uncore is supposed to be clocked at. In any case, the i3 530/540 results you see here should be close enough to shipping speed. And you can thank ASUS for that.
MSI was also kind enough to send us their H57M-ED65 for use in today's review

"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?
