A mobile version of Intel's Pentium 4 processor will begin appearing in notebooks during the first half of next year, an Intel executive said Wednesday. The Pentium 4 mobile chip, which will be made using the 0.13-micron manufacturing process, will be introduced at speeds of up to 1.5GHz and will reach speeds of 2GHz by the end of next year, said Frank Spindler, vice president and general manager of Intel's Mobile Platforms Group in his keynote at the Intel Developer Forum here on Wednesday. "You will see the Pentium 4 in mainstream, two-spindle, five- to six-pound notebooks at introduction," Spindler said. "We'll be able to build these in very high volumes and we'll also be able to support the Pentium 4 at various price points at its introduction." Currently, Intel's fastest mobile processor is the 0.13-micron mobile Pentium III, which runs at 1.13GHz. This processor, formerly known by its codename Tualatin, was launched by the company last month. Spindler demonstrated the Pentium 4 mobile chip for the first time Wednesday, showing a 2GHz version of the processor in action. In addition to the smaller circuit size, the mobile Pentium 4 will also feature an improved cache, a faster system bus and Intel's SpeedStep technology, which slows the speed of the processor while the system is unplugged, increasing battery life. "It will also take advantage of low power states, such as 'deep sleep'," Spindler said. Increasing battery life is Intel's current goal in the mobile-processor arena, Spindler said. To accomplish this, the vendor is trying to tweak the way a notebook uses its hard drive, DVD (digital versatile disc) drive, and display. Intel is also introducing its 830 chipset to the Pentium III Processor-M and attempting to decrease the amount of power used by the chipset itself and the graphics display, he said. "We believe that with these types of techniques, we can see a 30 per cent reduction in the amount of power needed to power notebooks," he said. Intel will also be introducing low-voltage and ultra-low voltage versions of the Pentium III Processsor-M later this year, he said. Spindler also referred to Intel's forthcoming mobile Banias processor, saying that introduction of the chip was targeted for the first half of 2003. Paul Otellini, the executive vice president and general manager of the Intel Architecture Group, lifted the veil on Banias in his keynote yesterday.
