Reasons to consider the
Intel Xeon E5-1603

Report a correction
Much higher clock speed 2.8 GHz vs 2.27 GHz Around 25% higher clock speed
Much more l3 cache 10 MB vs 4 MB 2.5x more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
Newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More threads 4 vs 2 Twice as many threads
More l3 cache per core 2.5 MB/core vs 2 MB/core 25% more l3 cache per core
Newer Mar, 2012 vs Feb, 2010 Release date over 2 years later
