Much more l3 cache 24 MB vs 18 MB Around 35% more l3 cache; more data can be stored in the l3 cache for quick access later
Much more l2 cache 3 MB vs 2 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
More threads 20 vs 16 4 more threads
Newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Supports more CPUs in SMP configuration 4 vs 2 Twice as many CPUs in SMP configuration
More l2 cache per core 0.3 MB/core vs 0.25 MB/core Around 20% more l2 cache per core
More l3 cache per core 2.4 MB/core vs 2.25 MB/core More than 5% more l3 cache per core
Newer Apr, 2011 vs Mar, 2010 Release date a year later
