Reasons to consider the
Intel Xeon X7460

Report a correction
Much more l2 cache 16 MB vs 8 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 2.66 GHz vs 2.33 GHz Around 15% higher clock speed
Supports more CPUs in SMP configuration 32 vs 2 30 supports more CPUs in SMP configuration
More cores 6 vs 4 2 more cores; run more applications at once
Much more l2 cache per core 2.67 MB/core vs 2 MB/core Around 35% more l2 cache per core
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
Better overclocked clock speed (Air) 2.81 GHz vs 2.7 GHz Around 5% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 2.67 GHz vs 2.33 GHz Around 15% better overclocked clock speed (Water)
Newer Sep, 2008 vs Nov, 2006 Release date over 1 years later
