Reasons to consider the
AMD A8 3870K

Report a correction
Much newer manufacturing process 32 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 4 MB vs 0.25 MB 16x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 3 GHz vs 1.53 GHz More than 95% higher clock speed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Much better overclocked clock speed (Air) 3.56 GHz vs 1.76 GHz More than 2x better overclocked clock speed (Air)
More cores 4 vs 1 3 more cores; run more applications at once
Better PassMark (Single core) score 1,032 vs 462 Around 2.2x better PassMark (Single core) score
Better PassMark score 3,596 vs 300 Around 12x better PassMark score
More threads 4 vs 1 3 more threads
Much better overclocked clock speed (Water) 3.67 GHz vs 1.53 GHz Around 2.5x better overclocked clock speed (Water)
