Reasons to consider the
Intel Xeon E3-1226 v3

Report a correction
Much higher clock speed 3.3 GHz vs 2.2 GHz Around 50% higher clock speed
Much more l3 cache 8 MB vs 1 MB 8x more l3 cache; more data can be stored in the l3 cache for quick access later
Much better PassMark score 7,554 vs 1,191 More than 6.2x better PassMark score
Much better PassMark (Single core) score 2,100 vs 684 More than 3x better PassMark (Single core) score
Much newer manufacturing process 22 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More cores 4 vs 2 Twice as many cores; run more applications at once
Much better performance per watt 19.03 pt/W vs 0.45 pt/W More than 42.5x better performance per watt
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much more l3 cache per core 2 MB/core vs 0.5 MB/core 4x more l3 cache per core
More threads 4 vs 2 Twice as many threads
Much better overclocked clock speed (Water) 3.93 GHz vs 2.2 GHz Around 80% better overclocked clock speed (Water)
Lower typical power consumption 68.25W vs 83.69W Around 20% lower typical power consumption
Significantly better overclocked clock speed (Air) 3.3 GHz vs 3.03 GHz Around 10% better overclocked clock speed (Air)
Newer Apr, 2014 vs Aug, 2006 Release date over 7 years later
Lower annual commercial energy cost 73.58 $/year vs 90.23 $/year Around 20% lower annual commercial energy cost
Lower annual home energy cost 20.24 $/year vs 24.81 $/year Around 20% lower annual home energy cost
