Budget-minded desktop owners do not have to lose hope in finding the right processor for their system. The humble yet capable AMD Athlon 64 LE-1640 is a single-core processor that sports a very low price tag and is energy-efficient to boot.
It has a thermal design power (TDP) of only 45 watts, which is pretty low considering its other features. The low TDP contributes much to its energy-efficiency since the rated TDP is actually the maximum power it will draw when running applications in real-time. So, you wouldnâ€™t have to worry about rigging up an ultra-expensive cooling system unless your configuration recommends otherwise.
