Intel shift over need for speed

The world’s largest chip maker, Intel, is changing its approach to making faster computer microprocessors. It has dropped plans to release a four gigahertz version of its flagship Pentium 4 chip. Intel’s shift reflects a change for the chip industry, which is moving away from boosts in megahertz and gigahertz. Instead it is looking to boost chip performance in ways other than simply increasing computational brainpower, also known as clock speed.
