Reasons to consider the
AMD Sempron 2800+

Report a correction
Much newer manufacturing process 90 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 1.6 GHz vs 0.5 GHz Around 3.2x higher clock speed
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much more l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Newer Jul, 2004 vs Oct, 1999 Release date over 4 years later
