From 2006-2012 the increase in the number of transistors on a chip has grown from 167 million to 2.6 billion, a 15x increase.<ref name="trans count"/>

From 2006-2012 the clock frequency has increased from 2.4ghz to 5.2, a 2.2x increase.<ref name="proc chrono"/>

IBM now has the 16-core processor Power PC A2, Intel has the 10 core Xeon E7, AMD has the 16 Opteron Interlagos, and Sun has the 8-core Niagara.<ref name="xeon"/><ref name="powerpc"/><ref name="amd"/><ref name="sun"/>
