Much higher turbo clock speed 4.1 GHz vs 0 GHz Compared to all cpus, 4.1 GHz turbo clock speed is just OK
Is unlocked Yes vs No Somewhat common; An unlocked multiplier allows for easier overclocking
Much more l2 cache 6 MB vs 4 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly higher clock speed 3.5 GHz vs 2.6 GHz Around 35% higher clock speed
Much newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 4.75 GHz vs 3.13 GHz More than 50% better overclocked clock speed (Air)
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Lower typical power consumption 77.19W vs 93.44W More than 15% lower typical power consumption
Much better overclocked clock speed (Water) 4.82 GHz vs 2.6 GHz More than 85% better overclocked clock speed (Water)
Higher Maximum operating temperature 62.5 °C vs 55 °C Around 15% higher Maximum operating temperature
Newer Oct, 2012 vs Feb, 2011 Release date over 1 years later
Lower annual home energy cost 22.89 $/year vs 27.7 $/year More than 15% lower annual home energy cost
Lower annual commercial energy cost 83.22 $/year vs 100.74 $/year More than 15% lower annual commercial energy cost
