Reasons to consider the
Intel Celeron M 353

Report a correction
Much newer manufacturing process 90 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Higher clock speed 0.9 GHz vs 0.6 GHz More than 50% higher clock speed
More l2 cache 0.5 MB vs 0.25 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Lower typical power consumption 4.06W vs 15.84W 3.9x lower typical power consumption
Newer Jul, 2004 vs Oct, 1999 Release date over 4 years later
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Lower annual home energy cost 1.2 $/year vs 4.7 $/year 3.9x lower annual home energy cost
Lower annual commercial energy cost 4.38 $/year vs 17.08 $/year 3.9x lower annual commercial energy cost
