Reasons to consider the
AMD FX 8120

Report a correction
Much more l2 cache 8 MB vs 1 MB 8x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
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 8 vs 1 7 more cores; run more applications at once
Newer Oct, 2011 vs Jan, 2005 Release date over 6 years later
More threads 8 vs 2 6 more threads
Significantly better overclocked clock speed (Air) 4.47 GHz vs 3.59 GHz Around 25% better overclocked clock speed (Air)
Better overclocked clock speed (Water) 4.73 GHz vs 4.18 GHz Around 15% better overclocked clock speed (Water)
