Clarkdale (microprocessor)
Encyclopedia
Clarkdale is the code name for an Intel processor, initially sold as desktop Intel Core i5 and Core i3 and Pentium. It is closely related to the
mobile Arrandale
processor; both use dual-core dies based on the 32 nm
Westmere version of the Nehalem microarchitecture and have integrated Graphics as well as
PCI Express
and DMI
links.
Clarkdale is the successor of the 45 nm Core microarchitecture-based Wolfdale
processor that is used in the many desktop Intel Core 2
, Celeron
and Pentium Dual-Core processors. While Wolfdale typically used both a north bridge
and a south bridge
, Clarkdale 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 Clarkdale 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. The CPUID
for Clarkdale is family 6, model 37 (2065x).

brand names, with varying feature sets. The Core i5 versions generally have all features enabled, with only the Core i5-661 model lacking Intel VT-d and TXT like the Core i3, which also does not support Turbo Boost
and the AES
new instructions. In addition, the Pentium and Celeron versions do not have SMT
, and they can only use a reduced amount of third-level cache.
The Xeon L340x line has a lower clock frequency and thermal design power, and supports unbuffered ECC memory
