Intel launching new chip lineup with circuit-shrinking technology SAN FRANCISCO (AP): Intel Corp. plans to roll out its newest generation of processors Monday, flexing its manufacturing muscle with a sophisticated new process that crams up to 40 percent more transistors onto the company's chips. The world's largest semiconductor company expects to start shipping 16 new microprocessors - which also boast inventive new materials to stanch electricity loss - for use in servers and high-end gaming PCs . The most complex chips being launched Monday have 820 million transistors, compared with the 582 million transistors on the same chips built using the current standard technology. Intel's first chips, introduced in the early 1970s, had just 2,300 transistors. Advances in chip technology occur as smaller and smaller lines are etched onto the chips. Intel's new chips shrink the width of those lines to an average of 45 nanometers, or 45 billionths of a meter, compared to 65 nanometers on the previous generation of chips . The smaller circuitry allows Intel to squeeze more transistors _ the building blocks of computer chips _ onto the same slice of silicon. That accelerates performance and drives down manufacturing costs. The transistors on the new chips are so small that more than 30 million of them can fit onto the head of a pin. Performance zooms ahead with smaller transistors because more of them are available, they twitch faster to process data and less energy is required to power them. Perhaps more importantly, the transistors on the company's new chips are built with new materials that help solve the critical problem of electricity loss as the circuitry gets smaller and smaller. As electricity escapes from the chip, more power is needed to fuel its operations, leading to shorter battery life in laptop computers or higher electricity costs to run the machines. ``This is more than just a new process shrink,'' Tom Kilroy, general manager of Intel's Digital Enterprise Group, said. ``Forty-five nanometers is wonderful and we get an uplift, but it really is the reinvention of the transistor.'' Intel, which plans to spend up to $8 billion (euro5.4 billion) on upgrading or building factories for the 45-nanometer chips, is at least six months ahead of smaller rival Advanced Micro Devices Inc. in moving to the new technology. Intel plans to launch new chips designed for mainstream desktop and laptop computers in the first quarter of 2008. AMD, which partners with IBM Corp. on chip-making technology, is targeting mid-2008 to start selling its 45-nanometer chips. AMD has long maintained that its chips have certain design advantages that keep them competitive with Intel's best offerings. One of those features is an integrated memory controller, which AMD has long championed. Intel only said recently it would begin incorporating the controllers into future generations of chips. ``When you get myopic on the focus on the nanometers in the CPU, you can lose focus on the entire solution,'' said AMD spokesman John Taylor. Intel's launch Monday includes server chips with frequencies of 2 gigahertz to 3.20 gigahertz for the quad-core models, which have four processing engines. The clock speed for dual-core models, which have two processing engines, goes up to 3.40 gigahertz. The measurements refer to the chips' processing cycles, or how fast they can process information. The server chips will sell for $177 to $1,279 (euro120 to euro871) in quantities of 1,000. The gaming chip will cost $999 (euro680) in quantities of 1,000.
