The 32nm Westmere mainstream processors from Intel will still use DMI rather than the newer QPI that is used on the Core i7 platform. FUD Zilla says this is good news for NVIDIA, because it's said that Intel isn't willing to grand NVIDIA a QPI license.
This is good news for Nvidia, since the company holds DMI chipset license for four years now, and they can probably build a chipset with better graphics compared to the one intel plans to stick in its multi chip module CPUs.
We do know that IGP graphics will be disabled once you plug in a discrete graphics card, but we wonder if Nvidia will be able to override Intel’s IGP and use the one from its chipset. The bad news for Nvidia is that buying an IGP chipset from Nvidia and plugging Arrandale or Clarkdale CPU on it will add cost to manufacturers and this will be Nvidia’s biggest problem.
