Is unlocked Yes vs No Somewhat common; An unlocked multiplier allows for easier overclocking
Significantly higher clock speed 3.5 GHz vs 2.5 GHz 40% higher clock speed
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much better overclocked clock speed (Air) 4.48 GHz vs 3.11 GHz Around 45% better overclocked clock speed (Air)
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
Significantly higher Maximum operating temperature 72.72 °C vs 55 °C More than 30% higher Maximum operating temperature
Newer Jun, 2013 vs Nov, 2008 Release date over 4 years later
More threads 8 vs 4 Twice as many threads
More l3 cache per core 2 MB/core vs 1.5 MB/core Around 35% more l3 cache per core
Much better overclocked clock speed (Water) 4.55 GHz vs 2.5 GHz More than 80% better overclocked clock speed (Water)
