Front view of AMD Sempron 2800+

Reasons to consider the
AMD Sempron 2800+

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
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Higher clock speed 1.6 GHz vs 1.4 GHz Around 15% higher clock speed
More l2 cache 0.5 MB vs 0.25 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Better overclocked clock speed (Air) 2.36 GHz vs 1.92 GHz Around 25% better overclocked clock speed (Air)
Better overclocked clock speed (Water) 1.8 GHz vs 1.4 GHz Around 30% better overclocked clock speed (Water)
Newer Jul, 2004 vs May, 2004 Release date 2 months later
