Reasons to consider the
Intel Xeon Phi 7120P

Report a correction
Much more l2 cache 30.5 MB vs 2 MB 15.2x more l2 cache; more data can be stored in the l2 cache for quick access later
More threads 244 vs 12 232 more threads
Supports more CPUs in SMP configuration 8 vs 1 7 supports more CPUs in SMP configuration
Significantly newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Newer Jun, 2013 vs Nov, 2012 Release date 7 months later
