Processors used for laptops are built a little differently from their Desktop and server counterparts. For one, they need to consume less power, which is limited in a mobile platform. Cooling options in laptops are limited: this requires the CPU to emit as little heat as possible. The two main CPU manufacturers, AMD and Intel, both have a slew of products for the mobile segment. These processors range from single cores in older models to quad cores in newer ones. AMD’s mobile processor range includes products like the dual-core Turion 64 X2 and Athlon 64 X2, and the single core Mobile Sempron, Mobile Athlon 64, and Turion 64. Intel markets mobile platforms under the name of Centrino, which collectively includes the processor, chipset, and wireless network adapter. Processors used in the Centrino platform are Pentium M, Core Solo, Core Duo, and Core 2 Duo. The Centrino platform has seen several implementations, like Carmel (2003), Sonoma (2005), Napa (2006), Santa Rosa (2007), and the proposed Montevina (2008) and Calpella (2009).
