Much more l2 cache 12 MB vs 2 MB 6x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l2 cache per core 3 MB/core vs 1 MB/core 3x more l2 cache per core
More cores 4 vs 2 Twice as many cores; run more applications at once
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 3.83 GHz vs 3.23 GHz Around 20% better overclocked clock speed (Air)
More threads 4 vs 2 Twice as many threads
Much better overclocked clock speed (Water) 4.1 GHz vs 2.8 GHz More than 45% better overclocked clock speed (Water)
Lower typical power consumption 65W vs 77.19W More than 15% lower typical power consumption
Lower annual commercial energy cost 70.08 $/year vs 83.22 $/year More than 15% lower annual commercial energy cost
Lower annual home energy cost 19.27 $/year vs 22.89 $/year More than 15% lower annual home energy cost
