Reasons to consider the
Intel Xeon E5-2690

Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better geekbench 2 (32-bit) score 20,376 vs 745 More than 27.2x better geekbench 2 (32-bit) score
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
More cores 8 vs 1 7 more cores; run more applications at once
More threads 16 vs 1 15 more threads
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
Newer Mar, 2012 vs Oct, 2005 Release date over 6 years later
Better overclocked clock speed (Air) 3.53 GHz vs 3.27 GHz Around 10% better overclocked clock speed (Air)
Higher Maximum operating temperature 72 °C vs 67.7 °C More than 5% higher Maximum operating temperature
Significantly better overclocked clock speed (Water) 3.92 GHz vs 2.93 GHz Around 35% better overclocked clock speed (Water)
