Reasons to consider the
Intel Core i5 480M

Report a correction
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much lower typical power consumption 28.44W vs 60.94W 2.1x lower typical power consumption
Newer Jan, 2011 vs Feb, 2009 Release date over 1 years later
Much lower annual home energy cost 8.43 $/year vs 18.07 $/year 2.1x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 65.7 $/year 2.1x lower annual commercial energy cost
Slightly better overclocked clock speed (Air) 3.07 GHz vs 2.9 GHz More than 5% better overclocked clock speed (Air)

Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher clock speed 2.9 GHz vs 2.66 GHz Around 10% higher clock speed
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
More l3 cache 6 MB vs 3 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
Better overclocked clock speed (Water) 2.9 GHz vs 2.67 GHz Around 10% better overclocked clock speed (Water)
