Reasons to consider the
Intel Atom 230

Report a correction
Much newer manufacturing process 45 nm vs 90 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
Much lower typical power consumption 3.25W vs 68.25W 21x lower typical power consumption
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
Significantly higher Maximum operating temperature 85.2 °C vs 67.7 °C More than 25% higher Maximum operating temperature
Newer Jun, 2008 vs Oct, 2004 Release date over 3 years later
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Much lower annual home energy cost 0.96 $/year vs 20.24 $/year 21x lower annual home energy cost
Much lower annual commercial energy cost 3.5 $/year vs 73.58 $/year 21x lower annual commercial energy cost
