Front view of AMD Sempron 140

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 1.4 GHz Around 95% higher clock speed
Much more l2 cache 1 MB vs 0.06 MB Around 16.8x 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 1.52 GHz Around 2.5x better overclocked clock speed (Air)
Much more l2 cache per core 1 MB/core vs 0.06 MB/core Around 16.8x 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 1.4 GHz More than 2.8x better overclocked clock speed (Water)
