Reasons to consider the
AMD Sempron 3850

Report a correction
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 28 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much lower typical power consumption 20.31W vs 69.06W 3.4x lower typical power consumption
Newer Dec, 2013 vs Feb, 2010 Release date over 3 years later
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Higher Maximum operating temperature 90 °C vs 77.6 °C More than 15% higher Maximum operating temperature
Much lower annual home energy cost 6.02 $/year vs 20.48 $/year 3.4x lower annual home energy cost
Much lower annual commercial energy cost 21.9 $/year vs 74.46 $/year 3.4x lower annual commercial energy cost
