Reasons to consider the
Intel Xeon E5-2698 v3

Report a correction
Much more l3 cache 40 MB vs 12 MB More than 3.2x more l3 cache; more data can be stored in the l3 cache for quick access later
Much higher clock speed 2.3 GHz vs 1.42 GHz More than 60% higher clock speed
More threads 32 vs 4 28 more threads
More cores 16 vs 2 14 more cores; run more applications at once
Much newer manufacturing process 22 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Much higher Maximum operating temperature 87.9 °C vs 76 °C More than 15% higher Maximum operating temperature
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Newer Jul, 2014 vs Oct, 2007 Release date over 6 years later
