Much more l3 cache 15 MB vs 8 MB Around 90% more l3 cache; more data can be stored in the l3 cache for quick access later
Supports more RAM 786,432 MB vs 147,456 MB Supports more than 5.2x more RAM
More cores 6 vs 4 2 more cores; run more applications at once
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
More threads 12 vs 8 4 more threads
Newer manufacturing process 22 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 l3 cache per core 2.5 MB/core vs 2 MB/core 25% more l3 cache per core
Newer Jan, 2014 vs Mar, 2009 Release date over 4 years later
