Reasons to consider the
Intel Pentium E5700

Report a correction
Much more l3 cache 2 MB vs None Compared to all cpus, 2 MB l3 cache is just OK
Much 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 more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Better overclocked clock speed (Water) 4.2 GHz vs 3.9 GHz Around 10% better overclocked clock speed (Water)

AMD A6 6400B

Report a correction
Much higher clock speed 3.9 GHz vs 3 GHz 30% higher clock speed
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
Newer Jun, 2013 vs Jul, 2010 Release date over 2 years later
