Reasons to consider the
AMD Phenom II N850

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
Higher clock speed 2.2 GHz vs 1.6 GHz Around 40% higher clock speed
Much lower typical power consumption 28.44W vs 84.5W 3x lower typical power consumption
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
Newer Oct, 2010 vs Jul, 2006 Release date over 4 years later
Much lower annual home energy cost 8.43 $/year vs 25.05 $/year 3x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 91.1 $/year 3x lower annual commercial energy cost
More cores 3 vs 2 1 more cores; run more applications at once
