Reasons to consider the
AMD Opteron 852

Report a correction
Much newer manufacturing process 90 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly higher clock speed 2.6 GHz vs 1.47 GHz More than 75% higher clock speed
Supports more CPUs in SMP configuration 8 vs 1 7 supports more CPUs in SMP configuration
Significantly more l2 cache 1 MB vs 0.25 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Better overclocked clock speed (Air) 2.76 GHz vs 2.11 GHz More than 30% better overclocked clock speed (Air)
Significantly better overclocked clock speed (Water) 2.6 GHz vs 1.47 GHz More than 75% better overclocked clock speed (Water)
