Much more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l3 cache 12 MB vs 8 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 6 vs 4 2 more cores; run more applications at once
Higher clock speed 2.26 GHz vs 2.13 GHz More than 5% higher clock speed
Higher turbo clock speed 2.8 GHz vs 2.53 GHz More than 10% higher turbo clock speed
More threads 12 vs 8 4 more threads
Newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More l2 cache per core 0.33 MB/core vs 0.25 MB/core Around 35% more l2 cache per core
