Arrandale is the code name for a family ofmobileIntel processors, sold as mobileIntel Core i3, i5 and i7 as well as Celeron and Pentium.[1][2] It is closely related to the desktopClarkdale processor; both use dual-core dies based on theWestmere32 nmdie shrink of theNehalem microarchitecture, and have integrated Graphics as well asPCI Express andDMI links.
Arrandale is the successor of the 45 nmCore-microarchitecture-basedPenryn processor that is used in many of the mobileCore 2,Celeron andPentium Dual-Core processors. While Penryn typically used both anorth bridge and asouth 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 nmprocessor die with the I/O connections, and the 45 nmIntel HD Graphics (Ironlake) controller and integrated memory controller die.[3] Physical separation of the processor die and memory controller die resulted in increased memory latency.
Arrandale was released on 7 January 2010, during CES 2010.[4] The code name Arrandale is named after its namesake place inBritish Columbia.
Arrandale processors were sold under theCeleron,Pentium,Intel Core i3,Intel Core i5 andIntel Core i7 brand names, with only the Core i7 models using the full L3 cache and all features. Processors ending in E instead of M are embedded versions with support for PCIe bifurcation andECC memory, while the regular mobile versions only support a single PCIe port and non-ECC memory.The Celeron versions of Arrandale have the smallest L3 cache of just 2 MB.[5]
