Reasons to consider the
AMD Turion II P520

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 lower typical power consumption 20.31W vs 68.25W 3.4x lower typical power consumption
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Newer May, 2010 vs Oct, 2005 Release date over 4 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
Much lower annual home energy cost 6.02 $/year vs 20.24 $/year 3.4x lower annual home energy cost
Much lower annual commercial energy cost 21.9 $/year vs 73.58 $/year 3.4x lower annual commercial energy cost
