Reasons to consider the
AMD R R-452L

Report a correction
Much more l2 cache 4 MB vs 1 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much lower typical power consumption 15.44W vs 77.19W 5x lower typical power consumption
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Much higher Maximum operating temperature 100 °C vs 72.7 °C Around 40% higher Maximum operating temperature
Newer May, 2012 vs Sep, 2009 Release date over 2 years later
Much lower annual home energy cost 4.58 $/year vs 22.89 $/year 5x lower annual home energy cost
Much lower annual commercial energy cost 16.64 $/year vs 83.22 $/year 5x lower annual commercial energy cost
