Reasons to consider the
AMD Athlon 1640B

Report a correction
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 newer manufacturing process 65 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 2.7 GHz vs 2.4 GHz Around 15% higher clock speed
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Much lower typical power consumption 36.56W vs 68.25W More than 45% lower typical power consumption
Much lower annual commercial energy cost 39.42 $/year vs 73.58 $/year More than 45% lower annual commercial energy cost
Much lower annual home energy cost 10.84 $/year vs 20.24 $/year More than 45% lower annual home energy cost
Better overclocked clock speed (Water) 2.7 GHz vs 2.4 GHz Around 15% better overclocked clock speed (Water)
