Intel's Nehalem microarchitecture has gone entirely mainstream with the arrival of the dual-core desktop processors code-named Clarkdale. This release also marks two major milestones: the first 32-nm processor, and the first major desktop CPU with integrated graphics. But is it a peanut butter and Vegemite sandwich? Hmm.
"The most notable new addition in the Clarkdale-focused versions of this chip is support for the Intel Flexible Display Interface (FDI), needed to pipe the IGP's graphics out to a display. The FDI interconnect is based on DisplayPort. The H55/H57/Q57 have two independent FDI links, one for each display supported, and each one has a 2.7Gbps data rate.
Beyond that, much in these chips will be familiar. The DMI interface handles all other communication between the Clarkdale package and the chipset, with aggregate data rates of up to 1 GB/s in each direction over its four pairs of unidirectional links. The PCIe x1 links on this chip remain Gen2-compliant but with only Gen1 data rates."
