Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.3 GHz vs 1.4 GHz More than 2.2x higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much lower typical power consumption 52.81W vs 84.5W Around 40% lower typical power consumption
Newer Jan, 2011 vs Jul, 2006 Release date over 4 years later
Much lower annual home energy cost 15.66 $/year vs 25.05 $/year Around 40% lower annual home energy cost
Much lower annual commercial energy cost 56.94 $/year vs 91.1 $/year Around 40% lower annual commercial energy cost
