Reasons to consider the
Intel E5-2683V4

Report a correction
Much more l3 cache 40 MB vs 20 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Much newer manufacturing process 14 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More cores 16 vs 8 Twice as many cores; run more applications at once
More threads 32 vs 16 Twice as many threads
Newer Jan, 2016 vs Mar, 2012 Release date over 3 years later
