Much more l3 cache 25 MB vs 15 MB More than 65% more l3 cache; more data can be stored in the l3 cache for quick access later
More threads 20 vs 6 14 more threads
Much better performance per watt 12.44 pt/W vs 3.2 pt/W Around 4x better performance per watt
More l2 cache 2.5 MB vs 2 MB 25% more l2 cache; more data can be stored in the l2 cache for quick access later
Higher turbo clock speed 3.6 GHz vs 3.4 GHz More than 5% higher turbo clock speed
Much better overclocked clock speed (Air) 3.4 GHz vs 2.9 GHz More than 15% better overclocked clock speed (Air)
Newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Lower typical power consumption 93.44W vs 105.63W More than 10% lower typical power consumption
Much better overclocked clock speed (Water) 3.49 GHz vs 2.9 GHz More than 20% better overclocked clock speed (Water)
Lower annual commercial energy cost 100.74 $/year vs 113.88 $/year More than 10% lower annual commercial energy cost
Lower annual home energy cost 27.7 $/year vs 31.32 $/year More than 10% lower annual home energy cost
Newer Jul, 2013 vs May, 2012 Release date over 1 years later
