Reasons to consider the
Intel Xeon E5-1428L

Report a correction
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l3 cache 15 MB vs 0.5 MB 30x more l3 cache; more data can be stored in the l3 cache for quick access later
Significantly newer manufacturing process 32 nm vs 40 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l3 cache per core 2.5 MB/core vs 0.25 MB/core 10x more l3 cache per core
More threads 12 vs 2 10 more threads
More cores 6 vs 2 Three times as many cores; run more applications at once
Newer Apr, 2012 vs Aug, 2011 Release date 7 months later
