Reasons to consider the
Intel Xeon E7450

Report a correction
Much more l2 cache 9 MB vs 2 MB 4.5x more l2 cache; more data can be stored in the l2 cache for quick access later
Supports more CPUs in SMP configuration 32 vs 1 31 supports more CPUs in SMP configuration
Much newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 2.4 GHz vs 2.13 GHz Around 15% higher clock speed
More cores 6 vs 2 Three times as many cores; run more applications at once
Much more l2 cache per core 1.5 MB/core vs 1 MB/core 50% more l2 cache per core
More threads 6 vs 2 Three times as many threads
Better overclocked clock speed (Air) 2.59 GHz vs 2.13 GHz More than 20% better overclocked clock speed (Air)
Better overclocked clock speed (Water) 2.4 GHz vs 2.13 GHz Around 15% better overclocked clock speed (Water)
