Much more l2 cache 1 MB vs 0.5 MB 2x 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
Significantly higher clock speed 3.7 GHz vs 3.3 GHz More than 10% higher clock speed
Much better overclocked clock speed (Air) 4.33 GHz vs 3.43 GHz More than 25% better overclocked clock speed (Air)
Much more l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Much higher Maximum operating temperature 71.3 °C vs 65.3 °C Around 10% higher Maximum operating temperature
Better overclocked clock speed (Water) 3.7 GHz vs 3.46 GHz More than 5% better overclocked clock speed (Water)
