Reasons to consider the
Intel Xeon X5690

Report a correction
Significantly higher clock speed 3.46 GHz vs 3.2 GHz Around 10% higher clock speed
Much 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
Much better PassMark score 9,059 vs 5,836 More than 55% better PassMark score
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
More cores 6 vs 4 2 more cores; run more applications at once
Much better performance per watt 7.01 pt/W vs 1.95 pt/W More than 3.5x better performance per watt
Higher turbo clock speed 3.73 GHz vs 3.46 GHz Around 10% higher turbo clock speed
Much better overclocked clock speed (Air) 4.47 GHz vs 3.53 GHz More than 25% better overclocked clock speed (Air)
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
More threads 12 vs 8 4 more threads
Supports more RAM 294,912 MB vs 147,456 MB Supports 2x more RAM
Newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Water) 4.97 GHz vs 4.04 GHz Around 25% better overclocked clock speed (Water)
More l2 cache per core 0.33 MB/core vs 0.25 MB/core Around 35% more l2 cache per core
Newer Feb, 2011 vs Mar, 2009 Release date over 1 years later
