New chips, concept computers and next-generation networking standards dominated the third day of Intel's developers conference in San Francisco yesterday. The chip-maker said it would produce a mobile version of its Pentium 4 chip this year and manufacturers are expected to announce high-end systems using the chips. The chips will use Intel's new 0.13 micron technology and be available at speeds of 1.5 gigahertz and higher. No low-power version is planned, as Intel claims the niche for low-power processors is filled by the mobile Pentium III. But next year, Intel plans to introduce its low-power Banias chips, designed for the mobile personal-computer market. On Wednesday, Intel demonstrated its 4GHz Prescott chip, which it plans to introduce next year on 0.09 micron technology. Prescott is the code name for the chip but there is no word on whether it will be branded as Pentium 4 or 5. Advanced Micro Devices (AMD), Intel's largest rival in central processing units, held an event nearby, where it demonstrated 64-bit chip technology. Most desktop processors use 32-bit architecture and Intel's only 64-bit chip, the Itanium, has not been widely adopted in the enterprise server market since it was introduced last year. AMD's demonstration suggests it intends to push 64-bit technology. Intel said clock speed was only one issue in the PC market. The company introduced concept PCs from its R&D unit with an emphasis on temperature, noise control and wireless connectivity. One concept PC, the Taishan, was developed in conjunction with Legend, China's largest PC maker. The concept PCs that received the most attention from attendees were the mobile prototypes. A 'flip-top' PC had a built-in component that acted very much like a personal digital assistant (PDA). It was designed to stay constantly connected to the Internet via wireless networking, constantly downloading e-mail and other information. Another prototype had built-in biometric security and a pull-out device that could be used as a mouse or a remote control. The company also demonstrated wireless roaming software that enables computers to detect nearby wireline, wireless or mobile data networks and change their settings accordingly. Intel is pushing for open standards on such software to move products and services into the market more quickly and thus increase demand for its chips. Security, authentication and billing would be key features in any standard, said Kurt Sehnert, technology manager at Intel Labs. 'Ideally, the user would be able to set up a policy, say, on whether he or she wants to be connected to for-fee networks and at what level of security,' he said. Intel is backing a number of next-generation PC standards. On the market this year will be USB 2.0, the new version of the universal standard for connecting devices such as cameras, stereos and PCs. Also, new varieties of the 802.11 standard for wireless networking and the DVI standard for digital media transfers will ship this year, though Intel executives said they did not expect them to become mainstream until next year. Further down the road are 3GIO and ultrawideband (UWB). The first is a device connection standard that PC makers can use to create plug-in modules for PCs, while the second is a short-range wireless technology to eliminate the tangle of wires that is familiar to any PC user who uses add-on hardware. Intel's semi-annual developers conference ends today.
