Reasons to consider the
Intel Xeon E5-2670 v3

Report a correction
Much more l3 cache 30 MB vs 20 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
More threads 24 vs 16 8 more threads
Supports more RAM 786,432 MB vs 393,216 MB Supports 2x more RAM
Much higher Maximum operating temperature 84.5 °C vs 80 °C More than 5% higher Maximum operating temperature
Newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Newer Jul, 2014 vs Mar, 2012 Release date over 2 years later
