Clarksfield is the code name for an Intel processor, initially sold as mobile Intel Core i7.[1] 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 Merom 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,[2] 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.[3]
Brand names
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 |
|---|---|---|---|
| Intel Core i7 | i7-7xxQM | 6 MB | 45 W |
| i7-8xxQM | 8 MB | ||
| i7-9xxXM Extreme Edition | 55 W |
