Report a correction
Much more l3 cache 30 MB vs 24 MB 25% more l3 cache; more data can be stored in the l3 cache for quick access later
Higher clock speed 2.4 GHz vs 2.26 GHz More than 5% higher clock speed
More threads 24 vs 20 4 more threads
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
Newer Jan, 2014 vs Apr, 2011 Release date over 2 years later
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
