Reasons to consider the
Intel Xeon E5 2640 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
Supports more RAM 786,432 MB vs 393,216 MB Supports 2x more RAM
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
Significantly better overclocked clock speed (Air) 2.55 GHz vs 2.28 GHz More than 10% better overclocked clock speed (Air)
