Reasons to consider the
Intel Xeon E7450

Report a correction
Much more l2 cache 9 MB vs 4 MB 2.2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l3 cache 12 MB vs 4 MB 3x more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 6 vs 2 Three times as many cores; run more applications at once
Newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More threads 6 vs 4 2 more threads
Newer Sep, 2008 vs Aug, 2006 Release date over 2 years later
