Reasons to consider the
AMD Opteron 8389

Report a correction
Much higher clock speed 2.9 GHz vs 2.3 GHz More than 25% higher clock speed
Much more l3 cache 6 MB vs 2 MB 3x more l3 cache; more data can be stored in the l3 cache for quick access later
Newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 2.9 GHz vs 2.43 GHz Around 20% better overclocked clock speed (Air)
Much more l3 cache per core 1.5 MB/core vs 0.5 MB/core 3x more l3 cache per core
Much better overclocked clock speed (Water) 2.9 GHz vs 2.3 GHz More than 25% better overclocked clock speed (Water)
Newer Feb, 2009 vs Apr, 2008 Release date 10 months later
