Reasons to consider the
Intel Xeon X5660

Report a correction
Much higher clock speed 2.8 GHz vs 2.1 GHz Around 35% higher clock speed
Much more l3 cache 12 MB vs 6 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Much better overclocked clock speed (Air) 4.13 GHz vs 2.1 GHz More than 95% better overclocked clock speed (Air)
Much higher Maximum operating temperature 81.3 °C vs 55 °C Around 50% higher Maximum operating temperature
More threads 12 vs 6 Twice as many threads
Much better overclocked clock speed (Water) 4.73 GHz vs 2.1 GHz More than 2.2x better overclocked clock speed (Water)
Newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l3 cache per core 2 MB/core vs 1 MB/core 2x more l3 cache per core
Newer Mar, 2010 vs Jul, 2009 Release date 8 months later
