Can anyone confirm which technology the new iMac 27" Intel i7 has: QuickPath Interconnect (QPI) or the slower DMI?

If you know, would you kindly provide proof?

I'm seriously thinking of buying the new iMac i7 and would like to get more information since Apple doesn't really provide that much.

Thanks.

The current iMac Core i5/i7 is based off of Lynnfield. The PCIe controler is onboard along with the memory controller.

The P55 PCH and other I/O controllers will connect over DMI to the processor and the supplementary PCIe lanes provided to the PCH.
