Reasons to consider the
AMD A8 7600

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
More cores 4 vs 2 Twice as many cores; run more applications at once
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Newer manufacturing process 28 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher Maximum operating temperature 71.3 °C vs 70 °C Almost the same
Newer Jul, 2014 vs Jun, 2013 Release date over 1 years later
