Could this be the reason why Intel mentioned that not all X58 motherboards would actually support the Westmere cores?
Good news for Nvidia
Clarkdale and Arrandale 32nm dual-cores with four threads and IGP on CPU will use DMI chipset interconnection rather than QPI, that is currently used on the X58 generation of chipsets.
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 Intelâ€™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 Nvidiaâ€™s biggest problem.
