Reasons to consider the
Intel Xeon E5-2630 v3

Report a correction
Much more l3 cache 20 MB vs 6 MB More than 3.2x more l3 cache; more data can be stored in the l3 cache for quick access later
Is unlocked Yes vs No Somewhat common; An unlocked multiplier allows for easier overclocking
Much better PassMark score 12,838 vs 2,951 More than 4.2x better PassMark score
More threads 16 vs 4 12 more threads
Significantly higher clock speed 2.4 GHz vs 2.2 GHz Around 10% higher clock speed
More cores 8 vs 4 Twice as many cores; run more applications at once
Newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 2.75 GHz vs 2.2 GHz Around 25% better overclocked clock speed (Air)
Much more l3 cache per core 2.5 MB/core vs 1.5 MB/core More than 65% more l3 cache per core
Newer Jul, 2014 vs Jan, 2009 Release date over 5 years later
Significantly better overclocked clock speed (Water) 2.4 GHz vs 2.2 GHz Around 10% better overclocked clock speed (Water)
