Clarksfield (microprocessor)
Encyclopedia
Clarksfield is the code name for an Intel processor, initially sold as mobile Intel Core i7. It is closely related to the desktop Lynnfield
processor, both use quad-core dies based on the 45 nm
Nehalem microarchitecture and have integrated PCI Express
and DMI
links.
The predecessor of Clarksfield, Penryn-QC was a multi-chip module
with two dual-core Penryn dies based on Penryn microarchitecture, a shrink of Core microarchitecture. The name of the direct successor of Clarksfield has not been announced. Arrandale
is a later mobile processor but opens a new line of mid-range dual-core processors with integrated graphics.
At the time of its release at the Intel Developer Forum
on September 23, 2009, Clarksfield processors were significantly faster than any other laptop processor, including the Core 2 Extreme QX9300. The initial laptop manufacturers shipping products based on Clarksfield processors include MSI, Dell/Alienware, Hewlett-Packard, Toshiba and Asustek.
See the respective lists for details about each model.
Lynnfield (microprocessor)
Lynnfield is the code name for a quad-core processor from Intel released in September 2009. It is sold in varying configurations as Core i5-7xx, Core i7-8xx or Xeon X34xx. Lynnfield uses the Nehalem microarchitecture and replaces the earlier Penryn based Yorkfield processor, using the same 45 nm...

Direct Media Interface
The Direct Media Interface is the link between an Intel northbridge and an Intel southbridge on a computer motherboard. It was first used between the 9xx chipsets and the ICH6, released in 2004. Previous chipsets had used the Hub Interface to perform the same function. Server chipsets use a...

Brand names
As of September 2009, all Clarksfield processors are marketed as Core i7, in three product lines differing in thermal design power and the amount of third-level cache that is enabled.See the respective lists for details about each model.
| Brand Name | Model (list) | L3 Cache size | Thermal Design Power Thermal Design Power The thermal design power , sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat... |
