While Penryn typically used both a north bridge and a south bridge, Arrandale already contains the major northbridge components, which are the memory controller, PCI Express bus for external graphics, integrated graphics, and the DMI interface, making it possible to build more compact systems. The Arrandale processor package contains two dies: the 32 nm processor die with the I/O connections, and the 45 nm
