Reasons to consider the
AMD Sempron 140

Report a correction
Much newer manufacturing process 45 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 2.7 GHz vs 1.47 GHz Around 85% higher clock speed
Much 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
Much better overclocked clock speed (Air) 3.69 GHz vs 2.11 GHz Around 75% better overclocked clock speed (Air)
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much better overclocked clock speed (Water) 3.93 GHz vs 1.47 GHz Around 2.8x better overclocked clock speed (Water)
