Reasons to consider the
Intel Atom E680T

Report a correction
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
Higher clock speed 1.6 GHz vs 1.33 GHz More than 20% higher clock speed
Better overclocked clock speed (Air) 1.6 GHz vs 1.33 GHz More than 20% better overclocked clock speed (Air)
Better overclocked clock speed (Water) 1.6 GHz vs 1.33 GHz More than 20% better overclocked clock speed (Water)

Reasons to consider the
Intel Atom E3825

Report a correction
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
More l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher GPU clock speed 533 MHz vs 400 MHz Around 35% higher GPU clock speed
Newer Oct, 2013 vs Sep, 2010 Release date over 3 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
