Front view of AMD Opteron 280

Reasons to consider the
AMD Opteron 280

Report a correction
Much higher clock speed 2.4 GHz vs 1.8 GHz Around 35% higher clock speed
Much 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
Significantly newer manufacturing process 90 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 2.67 GHz vs 2.17 GHz Around 25% better overclocked clock speed (Air)
More threads 2 vs 1 Twice as many threads
Much better overclocked clock speed (Water) 2.4 GHz vs 1.8 GHz Around 35% better overclocked clock speed (Water)
Newer Sep, 2005 vs Apr, 2003 Release date over 2 years later
