Reasons to consider the
Intel Xeon E5-4620 v2

Report a correction
Much higher turbo clock speed 3 GHz vs 0 GHz Compared to all cpus, 3 GHz turbo clock speed is just OK
Much more l3 cache 20 MB vs 12 MB More than 65% more l3 cache; more data can be stored in the l3 cache for quick access later
Much higher clock speed 2.6 GHz vs 2.2 GHz Around 20% higher clock speed
More threads 16 vs 8 Twice as many threads
Newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l3 cache per core 2.5 MB/core vs 1.5 MB/core More than 65% more l3 cache per core
Newer Jan, 2014 vs Feb, 2011 Release date over 2 years later
