===Shifts in market demand===

Increases in clock frequency have grown more slowly over the past few years, compared to power reduction improvements. This has been driven by the end of [[Moore's Law]] and demand for longer [[battery life]] and reductions in size for [[mobile technology]]. This change in focus from higher clock rates to power consumption and miniaturization can be shown by the significant reductions in power consumption, as much as 50%, that were reported by [[Intel]] in their release of the [[Haswell (microarchitecture)|Haswell microarchitecture]]; where they dropped their power consumption benchmark from 30-4030–40 [[Watt|watts]] down to 10-2010–20 watts.<ref>{{Cite web|url=http://www.intel.com/content/dam/doc/white-paper/resources-xeon-measuring-processor-power-paper.pdf|title=Measuring Processor Power TDP vs ACP|date=April 2011|website=Intel|access-date=5 May 2017}}</ref> Comparing this to the processing speed increase of 3 GHz to 4 GHz (2002 to 2006), it can be seen that the focus in research and development is shifting away from clock frequency and moving towards consuming less power and taking up less space.<ref>{{Cite web |date=24 April 2012 |title=History of Processor Performance |url=https://www.cs.columbia.edu/~sedwards/classes/2012/3827-spring/advanced-arch-2011.pdf |access-date=5 May 2017 |website=cs.columbia.edu}}</ref>
