Reasons to consider the
Intel Itanium 9130M

Report a correction
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Front view of Intel Atom D2550

Reasons to consider the
Intel Atom D2550

Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much lower typical power consumption 8.13W vs 84.5W 10.4x lower typical power consumption
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Higher clock speed 1.86 GHz vs 1.66 GHz More than 10% higher clock speed
Significantly higher Maximum operating temperature 100 °C vs 76 °C More than 30% higher Maximum operating temperature
Newer Mar, 2012 vs Oct, 2007 Release date over 4 years later
Much lower annual home energy cost 2.41 $/year vs 25.05 $/year 10.4x lower annual home energy cost
Much lower annual commercial energy cost 8.76 $/year vs 91.1 $/year 10.4x lower annual commercial energy cost
More threads 4 vs 2 Twice as many threads
