Reasons to consider the
Intel Core2 Quad Q9550

Report a correction
Much more l2 cache 12 MB vs 0.5 MB 24x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 2.83 GHz vs 0.9 GHz Around 3.2x higher clock speed
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache per core 3 MB/core vs 0.5 MB/core 6x more l2 cache per core
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
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
Much better overclocked clock speed (Air) 3.99 GHz vs 1.08 GHz Around 3.8x better overclocked clock speed (Air)
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
More cores 4 vs 1 3 more cores; run more applications at once
Newer Jan, 2008 vs Jul, 2004 Release date over 3 years later
Much better overclocked clock speed (Water) 4.03 GHz vs 0.9 GHz Around 4.5x better overclocked clock speed (Water)
More threads 4 vs 1 3 more threads
