Front view of Intel Xeon E5440

Reasons to consider the
Intel Xeon E5440

Report a correction
Much more l2 cache 12 MB vs 4 MB 3x more l2 cache; more data can be stored in the l2 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
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
Lower typical power consumption 65W vs 77.19W More than 15% lower typical power consumption
Much better overclocked clock speed (Water) 3.96 GHz vs 3.2 GHz Around 25% better overclocked clock speed (Water)
Lower annual commercial energy cost 70.08 $/year vs 83.22 $/year More than 15% lower annual commercial energy cost
Lower annual home energy cost 19.27 $/year vs 22.89 $/year More than 15% lower annual home energy cost
