Reasons to consider the
Intel Core2 Quad Q8300

Report a correction
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 4 MB vs 2 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Higher clock speed 2.5 GHz vs 2 GHz 25% higher clock speed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
More cores 4 vs 1 3 more cores; run more applications at once
Significantly better overclocked clock speed (Air) 3.32 GHz vs 2.35 GHz More than 40% better overclocked clock speed (Air)
Newer Nov, 2008 vs May, 2004 Release date over 4 years later
More threads 4 vs 1 3 more threads
Significantly better overclocked clock speed (Water) 3.33 GHz vs 2 GHz More than 65% better overclocked clock speed (Water)
