Much more l3 cache 35 MB vs 24 MB More than 45% more l3 cache; more data can be stored in the l3 cache for quick access later
Higher turbo clock speed 3 GHz vs 2.67 GHz More than 10% higher turbo clock speed
Much higher Maximum operating temperature 82.5 °C vs 69 °C Around 20% higher Maximum operating temperature
More threads 28 vs 20 8 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 97.5W vs 105.63W Around 10% lower typical power consumption
Newer Jul, 2014 vs Apr, 2011 Release date over 3 years later
Lower annual commercial energy cost 105.12 $/year vs 113.88 $/year Around 10% lower annual commercial energy cost
Lower annual home energy cost 28.91 $/year vs 31.32 $/year Around 10% lower annual home energy cost
