Reasons to consider the
Intel Xeon E7-8870

Report a correction
Much higher clock speed 2.4 GHz vs 1.6 GHz Around 50% higher clock speed
Much more l3 cache 30 MB vs 24 MB 25% more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 10 vs 2 8 more cores; run more applications at once
More threads 20 vs 4 16 more threads
Much more l2 cache 3 MB vs 2 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Supports more CPUs in SMP configuration 8 vs 4 Twice as many CPUs in SMP configuration
Newer Apr, 2011 vs Oct, 2007 Release date over 3 years later
