Reasons to consider the
AMD A8 4500M

Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 4 MB vs 2 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much lower typical power consumption 28.44W vs 101.56W 3.6x lower typical power consumption
Much higher Maximum operating temperature 100 °C vs 63 °C Around 60% higher Maximum operating temperature
Newer May, 2012 vs Nov, 2006 Release date over 5 years later
More cores 4 vs 2 Twice as many cores; run more applications at once
Much lower annual home energy cost 8.43 $/year vs 30.11 $/year 3.6x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 109.5 $/year 3.6x lower annual commercial energy cost
More threads 4 vs 2 Twice as many threads
