Reasons to consider the
Intel Xeon E5-4607 v2

Report a correction
Much more l3 cache 15 MB vs 10 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
Significantly higher clock speed 2.6 GHz vs 2.4 GHz Around 10% higher clock speed
More cores 6 vs 4 2 more cores; run more applications at once
More threads 12 vs 4 Three times as many threads
Supports more RAM 786,432 MB vs 393,216 MB Supports 2x more RAM
Newer manufacturing process 22 nm vs 32 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
Newer Jan, 2014 vs Mar, 2012 Release date over 1 years later
