Is unlocked Yes vs No Somewhat common; An unlocked multiplier allows for easier overclocking
Much newer manufacturing process 32 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly higher clock speed 3.5 GHz vs 2.3 GHz More than 50% higher clock speed
Significantly more l3 cache 15 MB vs 2 MB 7.5x more l3 cache; more data can be stored in the l3 cache for quick access later
Much better geekbench 3 single core score 3,376 vs 977.5 Around 3.5x better geekbench 3 single core score
Much better geekbench 3 Multi-Core score 19,564 vs 13,936 More than 40% better geekbench 3 Multi-Core score
Much more l3 cache per core 2.5 MB/core vs 0.5 MB/core 5x more l3 cache per core
Much better overclocked clock speed (Air) 4.57 GHz vs 2.43 GHz Around 90% better overclocked clock speed (Air)
Much better performance per watt 8.17 pt/W vs 2.16 pt/W More than 3.8x better performance per watt
More threads 12 vs 4 Three times as many threads
Newer Nov, 2012 vs Apr, 2008 Release date over 4 years later
More cores 6 vs 4 2 more cores; run more applications at once
Higher Maximum operating temperature 66.8 °C vs 55 °C More than 20% higher Maximum operating temperature
Much better overclocked clock speed (Water) 4.44 GHz vs 2.3 GHz Around 95% better overclocked clock speed (Water)
