Intel launched its mobile Pentium 4 architecture for the performance end of the notebook market last week at the IT Comdex trade show in Sydney. The chipmaker has introduced 1.6GHz and 1.7GHz chips as well as its 845MP chipsets with support for DDR 266MHz memory. Intel will release another chipset, the 845MZ, later this year. Based on the 0.13-micron architecture, the mobile Pentium 4 architecture combines the performance of the Pentium 4 chip with key power-saving technology. The technology switches between "maximum performance" mode and "battery optimised" mode, with the processor running at 1.2GHz to conserve power. Despite the emphasis on low power, the chips will be targeted at the performance end of the market, while Intel's mobile Pentium III chips will cover that part of the market for which power consumption is the focus. The 1.6GHz and 1.7GHz chips are priced at $US401 and $508 respectively in 1000-unit quantities, while the chipset costs $43.
