Front view of Intel Itanium 9340

Reasons to consider the
Intel Itanium 9340

Report a correction
More cores 4 vs 2 Twice as many cores; run more applications at once
More l3 cache 20 MB vs 18 MB More than 10% more l3 cache; more data can be stored in the l3 cache for quick access later
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
More threads 8 vs 4 Twice as many threads
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 Oct, 2007 Release date over 2 years later
