Much more l2 cache 6 MB vs 2 MB 3x more l2 cache; more data can be stored in the l2 cache for quick access later
Is unlocked Yes vs No Somewhat common; An unlocked multiplier allows for easier overclocking
Higher clock speed 3.5 GHz vs 2.9 GHz More than 20% 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 2.9 GHz Around 65% 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
Slightly more l3 cache 8 MB vs 6 MB Around 35% more l3 cache; more data can be stored in the l3 cache for quick access later
Newer Oct, 2012 vs Feb, 2009 Release date over 3 years later
More cores 6 vs 4 2 more cores; run more applications at once
More threads 6 vs 4 2 more threads
Higher Maximum operating temperature 62.5 °C vs 55 °C Around 15% higher Maximum operating temperature
Much better overclocked clock speed (Water) 4.82 GHz vs 2.9 GHz More than 65% better overclocked clock speed (Water)
