Reasons to consider the
AMD Opteron 6166 HE

Report a correction
Much more l2 cache 6 MB vs 1 MB 6x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
More cores 12 vs 2 10 more cores; run more applications at once
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
More threads 12 vs 2 10 more threads
Newer Feb, 2011 vs Jul, 2007 Release date over 3 years later
