AMD unveils line of energy-efficiency chips

@ 2006/05/16
AMD, however, will test them at the factory and those that consume electricity below a certain threshold will be sold as energy-efficient models. Making chips in a lot of ways is like cookies: they all come from the same dough, but each one is slightly different.

Consequently, the energy-efficient chips will cost slightly more than the standard variety. The energy-efficient dual-core Athlon X2 4800+ desktop chip sells for $671 in quantities of 1,000. The same chip with standard power consumption sells for $645.

Now you know why some overclock better with low heat; while others will go to the extreme to get a few mhz more.
