Quad Core Performance From Two Cores?
Intel released some preliminary performance data on Clarkdale. This data wasn't run by us and is straight from Intel. It's normalized to a Core 2 Duo E8500 and also includes a Core 2 Quad Q9400. The systems used G45 graphics for the LGA-775 parts and Clarkdale on-package graphics for the LGA-1156 setup.
We don't usually look at SPEC CPU performance, but here are the results regardless:
You can see that thanks to a competitive clock speed, aggressive turbo modes and Hyper Threading the 3.33GHz Clarkdale outperforms both the Q9400 and the E8500.
3DMark Vantage is of course faster on the newer platform thanks to the on-package graphics:
The overall performance improvement is roughly 50% in 3DMark Vantage.
Memory bandwidth is clearly better thanks to Clarkdale's on-die dual-channel DDR3 memory controller.
PCMark Vantage also shows a huge performance advantage on Clarkdale, however Intel mentioned that a big portion of that are the AES-NI instructions on Clarkdale accelerating one of the tests.
We'll be testing Clarkdale for ourselves later this year. It seems that this potent dual core with Hyper Threading could be a good alternative to making the quad-core jump.

That Cinebench score doesn't look that great, though I don't know the price of Clarkdale (would this fit into the ~$50-$100 bracket?). Otherwise, I'm excited to see these processors bring on more mini-itx proliferation and they look very capable processors.It's a good thing AMD has something to combat these processors in the form of it's Athlon II X4 line. Otherwise I'd say these, not Lynnfield or Bloomfield, would be the nail in the coffin for them.

So to summarize the Intel options for buyers: Basically Intel is going to offer the new 32nm process for super-high-end 6core setups and for HTPC-level dual-core budget systems, but the average gamer and enthusiast who just wants a middle-of-the-road, solid, high-performing cpu is going to be limited to 45nm Lynnfield P55 or an aging i7 920 on an X58 board?tim851 - Friday, September 25, 2009 - link
I'd reckon, that the entry level 6-core will be at the i7 920's price point, so that will be your sweet-spot CPU.Intel is probably pushing the Quads in the 100-200$ price segment and the Dual Cores below 100$.

Gulftown will start at $1k. Lynnfield will be the only Intel option for the budget gamer market segment (<$250 CPU, <$250 video card, no SLI) until Sandy Bridge. Stay away from the X58 platform, it's a dead-end money pit.MadMan007 - Friday, September 25, 2009 - link
I reckon you need to put down the crack pipe :D There's no way Gulftown will be ~$300.yacoub - Friday, September 25, 2009 - link
Not only that but that would require an X58 platform. What if you're running a P55? No 32nm love with more than 2 cores until late 2010 if at all? :(archcommus - Friday, September 25, 2009 - link
I agree as well. Although I'm not looking to upgrade right now anyway, I, like many others here I'm sure, have a Q6600 right now. I would want my next CPU to be a quad core with HT, preferrably 32nm, and have all the latest features like turbo mode and the on-die PCIe and memory controllers. Right now that option doesn't exist. If Westmere won't have a quad core option I guess we're just waiting for a Lynnfield die shrink.srue - Thursday, September 24, 2009 - link
I agree. I just want a 32nm Lynnfield.yacoub - Thursday, September 24, 2009 - link
Poor wording. Should replace "middle of the road" with "enthusiast overclocking system" because that's what I meant. I mean the type of CPU that's under $300 but more than 2 cores - what we've been building for the past couple years - there won't be a 32nm die shrink until SandyBridge and even then it will have more on the die than just a CPU.So for those of us building a gaming rig, who would rather not pay for an extra GPU or whatever on the die that we'd just end up disabling because we have a separate NVidia/AMD GPU on the PCIe bus, there is no 32nm die shrink on the horizon aside from a 6-core X58 chip?

There are some rumblings that we might see bloomfield and lynnfield get 32nm shrinks around the middle of next year.No evidence or links but it's possible.
