Much more l2 cache 12 MB vs 8 MB 50% 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 2 MB/core 50% more l2 cache per core
Significantly lower typical power consumption 65W vs 97.5W Around 35% lower typical power consumption
Newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Water) 4.07 GHz vs 2.66 GHz Around 55% better overclocked clock speed (Water)
Better overclocked clock speed (Air) 3.39 GHz vs 3.24 GHz Around 5% better overclocked clock speed (Air)
Significantly lower annual commercial energy cost 70.08 $/year vs 105.12 $/year Around 35% lower annual commercial energy cost
Significantly lower annual home energy cost 19.27 $/year vs 28.91 $/year Around 35% lower annual home energy cost
Newer Nov, 2007 vs Nov, 2006 Release date a year later
