Reasons to consider the
Intel Xeon L7345

Report a correction
Much more l2 cache 8 MB vs 0.5 MB 16x more l2 cache; more data can be stored in the l2 cache for quick access later
Supports more CPUs in SMP configuration 32 vs 1 31 supports more CPUs in SMP configuration
Much more l2 cache per core 2 MB/core vs 0.25 MB/core 8x more l2 cache per core
More cores 4 vs 2 Twice as many cores; run more applications at once
Slightly lower typical power consumption 40.63W vs 44.69W Around 10% lower typical power consumption
Slightly lower annual commercial energy cost 43.8 $/year vs 48.18 $/year Around 10% lower annual commercial energy cost
Slightly lower annual home energy cost 12.04 $/year vs 13.25 $/year Around 10% lower annual home energy cost

Report a correction
Much newer manufacturing process 22 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.3 GHz vs 1.86 GHz More than 75% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much better overclocked clock speed (Air) 3.43 GHz vs 1.87 GHz Around 85% better overclocked clock speed (Air)
Newer Sep, 2012 vs Sep, 2007 Release date over 5 years later
Much better overclocked clock speed (Water) 3.46 GHz vs 1.87 GHz More than 85% better overclocked clock speed (Water)
