Reasons to consider the
Intel Xeon E7-2803

Report a correction
Much lower typical power consumption 85.31W vs 172.6W 2x lower typical power consumption
More l3 cache 18 MB vs 12 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
Supports more RAM 1,048,576 MB vs 65,771.52 MB Supports around 16x more RAM
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Significantly more l3 cache per core 3 MB/core vs 2 MB/core 50% more l3 cache per core
Much lower annual home energy cost 25.29 $/year vs 56.96 $/year 2.3x lower annual home energy cost
Much lower annual commercial energy cost 91.98 $/year vs 177.83 $/year Around 50% lower annual commercial energy cost
