Reasons to consider the
AMD Opteron 2346 HE

Report a correction
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher clock speed 1.8 GHz vs 1.6 GHz More than 10% higher clock speed
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 4 vs 2 Twice as many threads
