Westmere has a small package

Note the 45nm integrated graphics
Intel prepares for its 32nm transition

Intel's P1268 32nm process is at an incredibly advanced stage, and Intel wants the world to know it.

The CPU behemoth has cancelled several 45nm products because it will have much more advanced 32nm products available this year. AMD, meanwhile, has only been selling 45nm chips since November.

Clarkdale is the desktop version of Westmere, built using two 32nm logic cores and a 45nm graphics core using Intel's "Multi-Chip Packaging". Targeted at the mainstream value market, it is capable of running four threads at once with Intel's newest generation of Hyper-Threading. A server variant of Clarkdale is also to be introduced later in Q1 of 2010.

Arrandale is the mobile version of Clarkdale and will also be available with integrated-on-package graphics. It will allow switchable graphics within Windows 7 and Windows Vista, enabling the use of a higher performance GPU through PCIe when plugged in.  Both Clarkdale and Arrandale will use 5 series chipsets exclusively with DDR3.

This is the first 32nm silicon out of Intel's Fab D1D Research and Development center in Hillsboro, Oregon. We were told that it is fully functional and running Windows 7. Intel also claims that its cycle times are greatly improved over its P1266 45nm process, and expects a faster ramp.

Power consumption numbers are visible for both Clarkdale and Arrandale, but these are just preliminary. Final production silicon will probably be much lower, but this gives a good indication of Intel's prowess.

We’d like to give a special thanks to Stephen Smith, Vice President and Director of Business Operations of Intel's Digital Enterprise Group, for making these pictures possible.

Only One Way

There's only one way I can think of at the moment, that this separate-die integration of GPU onto the CPU carrier is good. It will allow a single-interface heatsink design to cool both GPU and CPU. That is, so long as the system chipset is then reduced enough in heat density that it no longer needs anything more than a basic passive heatsink.

If these won't allow a basic passive heatsink for the system chipset, and I mean a very small cheap lightweight one equivalent to what we saw back in the Pentium 3 era, it was pointless. With that, you still need a 2nd chip for traditional chipset functions, that 2nd chip commonly being the IGP in lower-tiered products.

What this looks like is a reactionary design to combat nVidia who in all fairness should have had a larger share of the chipset market if it weren't for Intel bundling of CPU + chipset.

What we need is not this, it's a single chip solution integrating all functions you'd typically find in CPU, GPU, northbridge, southbridge. It MUST contain ALL these to make a significant difference in design size and cost, otherwise you're just playing a shell game with where the silicon is.

If a GPU gets integrated with EVERY Intel chip and they are programmable to handle massively parallel tasks then.. yes, this could be huge in and of itself (though those are some big IF's)

Hmmm, also forgot..as mentioned above, the ability to turn off the main GPU when not running anything graphically intensive (I'm assuming Aero is a breeze for these IGC) then that could save a third or more power when the computer isn't in a video game (which is probably most of the time).

You can't turn off the whole GPU, it handles 2D as well. Portions of it perhaps, but the same can be said about having it another chip as it already is with existing IGPs.

That won't matter, as already mentioned there's still the 2nd chip, that 2nd chip usually having the IGP that can still do the parallel tasks, EXCEPT, we have heard nothing from Intel about them doing parallel tasks, while we do already have examples of IGP from nVidia doing non-video processing.

Two dies on one carrier is great when it gets rid of a 2nd chip/carrier, as mentioned previously it would be great news to me if they didn't do it halfway and integrated the entire chipset but since they don't, it has limited usefulness.

One thing your not recognizing here, this is not the socket replacement for the I7. This is the 4 core socket for the new chipset (value I7 1266 or something like that)Intel will be releasing between now and school starting next fall. The replacement on the current I7 chipset will be 8 cores. And I believe as I had read a day or two ago the current X58 boards will not apply to this CPU. There will also be a direct replacement on the current I7 1366 chipset, that will be 32nm as well. From what I understood the 4 core 32nm with the graphics core was value and I think is called the I5.

You are wrong.

Gulftown is the new 6-core CPU, not 8-core, coming next year, and can use the X58 chipset.

The Core i5 is 45nm and doesn't have have on package graphics, it is just mainstream Nehalem.
