Reasons to consider the
AMD Athlon II X2 240

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
Significantly higher clock speed 2.8 GHz vs 1.8 GHz More than 55% higher clock speed
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Significantly better overclocked clock speed (Air) 3.67 GHz vs 2.4 GHz Around 55% better overclocked clock speed (Air)
Newer Jul, 2009 vs Apr, 2004 Release date over 5 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
Significantly better overclocked clock speed (Water) 2.8 GHz vs 1.8 GHz More than 55% better overclocked clock speed (Water)
