Much more l2 cache 4 MB vs 1 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher clock speed 3.4 GHz vs 3.1 GHz Around 10% higher clock speed
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 4 vs 2 Twice as many threads
Much better overclocked clock speed (Air) 4.46 GHz vs 3.21 GHz Around 40% 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
Much better overclocked clock speed (Water) 5.01 GHz vs 3.1 GHz More than 60% better overclocked clock speed (Water)
