Reasons to consider the
Intel Xeon E5-2640

Report a correction
Much newer manufacturing process 32 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 2 MB vs 0.25 MB 8x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly higher clock speed 2.5 GHz vs 1.58 GHz Around 60% higher clock speed
Much better PassMark score 15,348 vs 464 More than 33x better PassMark score
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much better PassMark (Single core) score 1,854 vs 622 Around 3x better PassMark (Single core) score
More cores 6 vs 1 5 more cores; run more applications at once
More threads 12 vs 1 11 more threads
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
Newer Mar, 2012 vs Jul, 2004 Release date over 7 years later
Significantly better overclocked clock speed (Air) 2.9 GHz vs 2.04 GHz More than 40% better overclocked clock speed (Air)
More l2 cache per core 0.33 MB/core vs 0.25 MB/core Around 35% more l2 cache per core
Significantly better overclocked clock speed (Water) 2.5 GHz vs 1.58 GHz Around 60% better overclocked clock speed (Water)
