Reasons to consider the
Intel Celeron M 440

Report a correction
Much newer manufacturing process 65 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much 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
Much better performance per watt 1.7 pt/W vs 0.41 pt/W More than 4x better performance per watt
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Much better overclocked clock speed (Air) 3.57 GHz vs 2.21 GHz More than 60% better overclocked clock speed (Air)
Higher clock speed 2 GHz vs 1.75 GHz Around 15% higher clock speed
Significantly lower typical power consumption 28.44W vs 47.94W More than 40% lower typical power consumption
Much better overclocked clock speed (Water) 3.98 GHz vs 1.4 GHz More than 2.8x better overclocked clock speed (Water)
Significantly lower annual home energy cost 8.43 $/year vs 14.21 $/year More than 40% lower annual home energy cost
Significantly lower annual commercial energy cost 30.66 $/year vs 51.68 $/year More than 40% lower annual commercial energy cost
Newer Jul, 2006 vs Jul, 2004 Release date over 1 years later
