Reasons to consider the
Intel Xeon L5630

Report a correction
Much more l3 cache 12 MB vs 8 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
Much lower typical power consumption 32.5W vs 69.06W 2.1x lower typical power consumption
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 3 MB/core vs 2 MB/core 50% more l3 cache per core
Much lower annual commercial energy cost 35.04 $/year vs 74.46 $/year 2.1x lower annual commercial energy cost
Much lower annual home energy cost 9.64 $/year vs 20.48 $/year 2.1x lower annual home energy cost
