Reasons to consider the
Intel Itanium 9310

Report a correction
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Newer manufacturing process 65 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Supports more CPUs in SMP configuration 8 vs 4 Twice as many CPUs in SMP configuration
Newer Feb, 2010 vs Jul, 2006 Release date over 3 years later
