Reasons to consider the
Intel Xeon X5670

Report a correction
Much more l3 cache 12 MB vs 1 MB 12x more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 6 vs 2 Three times as many cores; run more applications at once
More threads 12 vs 2 10 more threads
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher Maximum operating temperature 81.3 °C vs 55 °C Around 50% higher Maximum operating temperature
Much better overclocked clock speed (Air) 4.29 GHz vs 3 GHz Around 45% better overclocked clock speed (Air)
Much more l3 cache per core 2 MB/core vs 0.5 MB/core 4x more l3 cache per core
Lower typical power consumption 77.19W vs 96.69W More than 20% lower typical power consumption
Much better overclocked clock speed (Water) 4.5 GHz vs 3 GHz Around 50% better overclocked clock speed (Water)
Newer Mar, 2010 vs Aug, 2007 Release date over 2 years later
Lower annual commercial energy cost 83.22 $/year vs 104.24 $/year More than 20% lower annual commercial energy cost
Lower annual home energy cost 22.89 $/year vs 28.67 $/year More than 20% lower annual home energy cost
