Reasons to consider the
AMD A8 5550M

Report a correction
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
Higher clock speed 2.1 GHz vs 1.55 GHz More than 35% higher clock speed
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
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 0.5 MB/core 2x more l2 cache per core
Significantly higher Maximum Operating Temperature 105 °C vs 90 °C More than 15% higher Maximum Operating Temperature
