Intel introduces laptop chips to challenge AMD

Intel rolled out a new batch of chips for laptops that promise longer battery life and better graphics-rendering abilities, the company's latest salvo against feisty smaller rival Advanced Micro Devices。
Both companies hope to capture the attention of computer buyers looking for crisper high-definition video playback on their laptops and less battery drain, a difficult balancing act.
The latest from Intel is its Centrino 2 "platform" -- a package that includes a processor, related chipset and wireless communications chip.
Intel is releasing five new processors in different versions of the bundle. Three of those use just 25 watts of energy, a 30 percent reduction from the previous generation.
Intel has an advantage in power consumption because it has moved faster than AMD to a manufacturing process that lowers the energy use of its chips and the cost of making them.
AMD, meanwhile, has dramatically improved the visual capabilities of its chips with the 2006 acquisition of graphics chip maker ATI Technologies, a $5.6 billion deal that saddled AMD with substantial debt.
AMD overhauled its mobile lineup last month with the release of its new Turion processor and related chipset.
Also at stake is Intel's need to push a new long-range wireless Internet technology called WiMax. Intel has invested heavily in WiMax, but the technology has serious competition.
Intel plans to introduce WiMax technologies into the Centrino 2 bundle later this year。
