Reasons to consider the
Intel Xeon E5-2440 v2

Report a correction
Much more l3 cache 20 MB vs 15 MB Around 35% more l3 cache; more data can be stored in the l3 cache for quick access later
Much better performance per watt 7.05 pt/W vs 2.28 pt/W More than 3x better performance per watt
More threads 16 vs 12 4 more threads
Newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Newer Jan, 2014 vs May, 2012 Release date over 1 years later
