Report a correction
Much more l2 cache 4 MB vs 2 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher clock speed 3.4 GHz vs 2.8 GHz More than 20% higher clock speed
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 more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Much better overclocked clock speed (Air) 4.17 GHz vs 2.8 GHz Around 50% better overclocked clock speed (Air)
Significantly higher Maximum operating temperature 71.3 °C vs 55 °C Around 30% higher Maximum operating temperature
Newer Oct, 2012 vs Feb, 2009 Release date over 3 years later
Lower typical power consumption 52.81W vs 60.94W Around 15% lower typical power consumption
Better overclocked clock speed (Water) 3.4 GHz vs 2.8 GHz More than 20% better overclocked clock speed (Water)
Lower annual commercial energy cost 56.94 $/year vs 65.7 $/year Around 15% lower annual commercial energy cost
Lower annual home energy cost 15.66 $/year vs 18.07 $/year Around 15% lower annual home energy cost
