and Pentium Dual-Core processors. Unlike its predecessor, Clarkdale already contains the major north bridge components, such as memory controller, PCI Express for external graphics, integrated graphics and the DMI connector, making it possible to build more compact systems without a separate north bridge or discrete graphics like Lynnfield. The Clarkdale processor package contains two dies: the 32 nm processor die with the I/O connections, and the 45 nm graphics and integrated memory controller die. Physical separation of the processor die and memory controller die resulted in increased memory latency. The CPUID for Clarkdale is family 6, model 37 (2065x). The mobile equivalent of Clarkdale is Arrandale.
