The time has come for Intel to debut a new line of mainstream 32nm processors, which we have all learned to recognize under the codename 'Clarkdale'. The new CPUs will be aimed at the mainstream desktop PC segment and will complement the chip maker's Core i3 and Core i5 line of products.
The new Intel processor lineup will include the Core i3 530 and 540 models, as well as the Core i5 650, 660, 661, and 670, which will be featured with Hyper-Threading, 4MB of L3 cache and support for dual-channel DDR3-1333 memory. Well, that and an integrated GPU as well of course. Guru3D will put the Core i5 650, 660 and 661 to the test.

Cheers for that Mathwat, really interesting read.

The on-board IGP is a strange thing, but as stated will be great for Htpc builds.

I still think the king of cpu's currently is the i7 920 do stepping though, purely for it's performance/price point (otherwise it would be the 975 obv)

Looking forward to all the new 5 core processors and such, roll on 2010!
 
Nice idea. A lot of people don't need fancy graphics myself included.

I'm looking for a new system for a work environment mainly for MatLab modelling and some image processing. An i5 750 would be a good solution - but if available I'd like built in graphics on the CPU or MB. There's no way to get built in graphics on an i5 750 board is there?

for what your needing you might need a proper graphics card. Will help you out a lot. onboard i wouldnt count on it.

i5 750 and a new 5750 graphics card to keep the cost and power consumption down. Just so you can save money on a powersupply :)

As always, Tech Report has one of the best reviews
As a CPU technology, Clarkdale is excellent. I can't get over how the Core i5-661 kept nearly matching the Core 2 Quad Q9400 in things like video encoding and rendering with just two cores. We've known for a while how potent the Nehalem microarchitecture can be, but seeing a dual-core processor take on a quad-core from the immediately preceding generation is, as I said, pretty mind-blowing. Clarkdale's power consumption is admirably low at peak, as well, and its idle power draw of only 42W on the Intel H55 board during our IGP tests was quite the statement. There are only two little weaknesses I can name. First, when installed in our P55 motherboard, the Core i5-661 had the same power draw at idle as the Core i5-750. With its two 32-nm cores, I had hoped its idle power draw might be measurably lower. Second, the dual-chip package has apparently produced relatively high memory access latencies. Those higher latencies obviously didn't hamper performance too much, but they may explain why the Core i5-661 wasn't much faster than the Core 2 Duo E8600 in a number of lightly threaded application, including WorldBench's Office, Firefox, and WinZip tests.

Looks like there is loads of overclocking headroom in these 32nm chips

As a result, Core i5-661 processor with the default frequency of 3.33 GHz and 1.16875 V nominal core voltage overclocked to 4.4 GHz.

4.4Ghz on 1.16875 is pretty impressive. Throw in watercooling and some more volts and 5Ghz looks reachable.
