After the Bloomfield office on socket 1366 in November 2008 and after the Lynnfield desktop on socket 1156, Intel continues to decline his Nehalem architecture with the release of Core i7 CPUs Mobile "Clarksfield" for laptops. Three quad-core models are launched and this is more of processors designed to take place in large laptops than lighter models.The TDP of 45 watts confirmed. In reality they succeed the Core 2 Quad mobile whose destination was the same.

Who says new mobile processors, says new Centrino platform, already the sixth. Indeed, in March 2003 it has appeared for the first time the name Centrino platform with the Carmel-based socket 479 Pentium M Banias and Dothan and torque 855/ICH4M chipset. It was not until January 2005 to come see the Sonoma platform, which consisted of a 915 chipset with the ICH6M while the processor was a Pentium M Dothan 90 nanometers, still on socket 479. A year later, in January 2006, unsheathed the Intel Napa platform, which inaugurated the Core architecture processors with Yonah Core Duo and Core Solo engraved in 65 nanometers. The chipset was the 945 Express seconded by ICH7M. During 2006, Intel released processors Merom derivatives Core 2 Duo, always engraved in 65 nanometers.

In May 2007 the fate Santa Rosa platform with torque Chipeta 965/ICH8M. This platform will begin his career with the Core 2 Solo and Duo "Merom" before the arrival of Core 2 Solo and Duo-based architecture Penryn processors then etched in 45 nanometers. In June 2008, the Centrino brand is now in version 2 and Centrino 2 is then called Montevina platform. The program chipset Series 4 Express and the Southbridge ICH9M. As for the processors are kept Penryn Core 2 Duo and we welcome the arrival of the first quad-core mobile Core 2 Quad Mobile. The sixth generation for its part, was launched last September 23 and is called, sing it all by heart, Calpella. It uses a P55 Express chipset and southbridge not seen that P55 is somewhere office southbridge while the processor includes 16 lines PCI-Express and DDR3 memory controller.

We had the opportunity to play with an Acer laptop based on this new platform Calpella and compared to an Asus laptop with the older generation Montevina and a Core 2 Quad Q9000 Mobile.
