Report a correction
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 2.83 GHz vs 1.6 GHz More than 75% higher clock speed
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
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
More cores 4 vs 2 Twice as many cores; run more applications at once
Lower typical power consumption 77.19W vs 84.5W Around 10% lower typical power consumption
Newer Jan, 2008 vs Jul, 2006 Release date over 1 years later
Lower annual home energy cost 22.89 $/year vs 25.05 $/year Around 10% lower annual home energy cost
Lower annual commercial energy cost 83.22 $/year vs 91.1 $/year Around 10% lower annual commercial energy cost
