Reasons to consider the
AMD A10 7400P

Report a correction
Much newer manufacturing process 28 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly higher clock speed 2.5 GHz vs 1.42 GHz More than 75% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
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 May, 2014 vs Jul, 2006 Release date over 7 years later
Much higher Maximum operating temperature 102 °C vs 76 °C Around 35% higher Maximum operating temperature
More cores 4 vs 2 Twice as many cores; run more applications at once
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
