Reasons to consider the
Intel Atom D525

Report a correction
Much newer manufacturing process 45 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly more l2 cache 1 MB vs 0.25 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher clock speed 1.8 GHz vs 1.4 GHz Around 30% higher clock speed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Newer Jun, 2010 vs May, 2004 Release date over 6 years later
Lower typical power consumption 10.56W vs 20.31W Around 50% lower typical power consumption
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Better performance per watt 2.62 pt/W vs 0.48 pt/W More than 5.5x better performance per watt
More threads 4 vs 1 3 more threads
More cores 2 vs 1 Twice as many cores; run more applications at once
Slightly better overclocked clock speed (Air) 2.12 GHz vs 1.92 GHz More than 10% better overclocked clock speed (Air)
Lower annual home energy cost 3.13 $/year vs 6.02 $/year Around 50% lower annual home energy cost
Lower annual commercial energy cost 11.39 $/year vs 21.9 $/year Around 50% lower annual commercial energy cost
Better overclocked clock speed (Water) 1.8 GHz vs 1.4 GHz Around 30% better overclocked clock speed (Water)
