As components shrink, chip makers struggle to get more performance out of them while meeting power needs.
Research suggests relaxing the rules governing how they work and when they work correctly could mean they use less power but get a performance boost.
Special software is also needed to cope with the error-laden chips.
The silicon industry is defined by Moore's Law, which predicts that the number of transistors that can fit on a given area of silicon, for a given price will double every 18-24 months.
This is usually accomplished by shrinking transistors and typically means that processing steadily gets more powerful.
However, many experts point out that the relentless march of Moore's Law could stumble when components get so small they become unreliable.
