Reasons to consider the
Intel Xeon L5215

Report a correction
Much more l2 cache 6 MB vs 3 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l2 cache per core 3 MB/core vs 1.5 MB/core 2x more l2 cache per core
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much lower typical power consumption 16.25W vs 52.81W 3.2x lower typical power consumption
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
Much lower annual home energy cost 4.82 $/year vs 15.66 $/year 3.2x lower annual home energy cost
Much lower annual commercial energy cost 17.52 $/year vs 56.94 $/year 3.3x lower annual commercial energy cost
Newer Jul, 2008 vs Apr, 2008 Release date 3 months later
