Reasons to consider the
Intel Xeon E5-2430

Report a correction
Much more l2 cache 2 MB vs 0.5 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly more l3 cache 15 MB vs 6 MB 2.5x more l3 cache; more data can be stored in the l3 cache for quick access later
More threads 12 vs 2 10 more threads
More cores 6 vs 2 Three times as many cores; run more applications at once
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
More l2 cache per core 0.33 MB/core vs 0.25 MB/core Around 35% more l2 cache per core
