Arrandale is the code name for a mobile Intel processor[clarification needed], sold as mobile Intel Core i3, i5 and i7 as well as Celeron and Pentium.[1][2] It is closely related to the desktop Clarkdale processor; both use dual-core dies based on the 32 nm Westmere shrink of the Nehalem microarchitecture and have integrated Graphics as well as PCI Express and DMI links.
Arrandale is the successor of the 45 nm Core microarchitecture based Penryn processor that is used in the many mobile Intel Core 2, Celeron and Pentium Dual-Core processors. While Penryn typically used both a north bridge and a south bridge, Arrandale already contains the major north bridge components, which are the memory controller, PCI Express for external graphics, integrated graphics and the DMI connector, making it possible to build more compact systems without a separate northbridge or discrete graphics as Lynnfield. The Arrandale processor package contains two dies, the actual 32 nm processor with the I/O connections and the 45 nm graphics controller with the memory interface.[3]
Arrandale was released on 7 January 2010, during CES 2010.[4]
[edit] Brand names
Arrandale processors are sold under the Celeron, Pentium, Intel Core i3, Intel Core i5 and Intel 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 and ECC 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.
