Intel Ready for On-die GPU with Core i5/i7

“The floor plan above shows the main blocks in Nehalem, and if you've followed previous Nehalem launches (most notably Bloomfield) then you may be able to spot what's missing: there is no QuickPath Interconnect (QPI) interface. Instead, in a significant twist that differentiates Intel's new PC system architecture from even AMD's offerings, there is now a PCIe interface that enables the GPU to attach directly to the processor socket. This latter move was made in anticipation of two things: 1) the GPU will migrate right into the processor socket at a later point when Intel releases a CPU with an on-die GPU integrated into it, and 2) for a discrete GPU, Intel hopes you'll use Larrabee.”
