Reasons to consider the
Intel Xeon E5430

Report a correction
Much more l2 cache 12 MB vs 8 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 2.66 GHz vs 2.13 GHz Around 25% higher clock speed
Much more l2 cache per core 3 MB/core vs 2 MB/core 50% 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
Much better overclocked clock speed (Air) 3.39 GHz vs 2.91 GHz More than 15% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 4.07 GHz vs 2.67 GHz Around 55% better overclocked clock speed (Water)
