Reasons to consider the
Intel Xeon E5 4657L v2

Report a correction
Much more l3 cache 30 MB vs 15 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
More threads 24 vs 12 Twice as many threads
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Lower typical power consumption 93.44W vs 105.63W More than 10% lower typical power consumption
Lower annual home energy cost 27.7 $/year vs 31.32 $/year More than 10% lower annual home energy cost
Lower annual commercial energy cost 100.74 $/year vs 113.88 $/year More than 10% lower annual commercial energy cost
Newer Jan, 2014 vs Sep, 2013 Release date 4 months later
