Front view of Intel Xeon E7-8830

Reasons to consider the
Intel Xeon E7-8830

Report a correction
Much more l3 cache 24 MB vs 1 MB 24x more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 8 vs 2 6 more cores; run more applications at once
More threads 16 vs 2 14 more threads
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l3 cache per core 3 MB/core vs 0.5 MB/core 6x more l3 cache per core
Newer Apr, 2011 vs Aug, 2006 Release date over 4 years later
