Reasons to consider the
Intel Xeon E6510

Report a correction
Much lower typical power consumption 85.31W vs 139.6W Around 40% lower typical power consumption
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
Slightly more l3 cache 12 MB vs 10 MB 20% more l3 cache; more data can be stored in the l3 cache for quick access later
More l3 cache per core 3 MB/core vs 2.5 MB/core 20% more l3 cache per core
Much lower annual home energy cost 25.29 $/year vs 49.49 $/year Around 50% lower annual home energy cost
Much lower annual commercial energy cost 91.98 $/year vs 138.93 $/year Around 35% lower annual commercial energy cost
