Reasons to consider the
Intel Core i3 3220

Report a correction
Much newer manufacturing process 22 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.3 GHz vs 1.3 GHz More than 2.5x higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
More threads 4 vs 1 3 more threads
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
More cores 2 vs 1 Twice as many cores; run more applications at once
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
Newer Sep, 2012 vs Jun, 2004 Release date over 8 years later
Much better overclocked clock speed (Water) 3.46 GHz vs 2.4 GHz Around 45% better overclocked clock speed (Water)
Better overclocked clock speed (Air) 3.43 GHz vs 3.37 GHz Almost the same
