Intel keeps chipping away

The new processors include mobile Pentium IIIs running at 750MHz and 600MHz, and a trio of mobile Celerons running at 650MHz, 600MHz and 500MHz.

The 600MHz Pentium III is the first performance processor from Intel to consume less than one watt of power on average, making it well suited for use in ultraportable notebooks such as Sony's Vaio, officials said. The processor has been designed in such a way that it can drop its power consumption when the processor is not actually doing any work, the officials said.

Also aimed at the ultraportable market is the 500MHz Celeron, which consumes less than 2 watts of power on average, Intel officials said. The Celeron family is aimed at the value segment of the PC market.

Intel officials this week would not be drawn on exactly how much additional battery life the power-saving chips will bring. Battery life depends on a multitude of factors, most of which have more to do with overall design of a PC than the processor itself, said Frank Spindler, vice president and general manager of Intel's mobile products group.

"If everything else [in the PC system] is identical, you should see more and more performance without any sacrifice to battery life," Spindler said.

The new processors have been shipping to PC makers for a month or more, and should be available soon in notebooks from Dell, Toshiba, Sony, Compaq, NEC, and others, Spindler said.

Building low-power processors has become a major focus for chipmakers, as users seek out notebooks with longer battery life. Transmeta sent a ripple through the PC chip industry in January when it unveiled its Crusoe chips, which the company claimed can be used to build notebooks with all-day battery life. Transmeta is expected to announce customers for its Crusoe 5400 notebook chip at the PC Expo conference in New York next week.

Intel, meanwhile, introduced its Speedstep technology in January, which allows its mobile processor to drop to a slower speed when a notebook is unplugged from a main outlet. The 750MHz mobile Pentium III launched Monday, for example, drops to 600MHz when the notebook is running on a battery.

Spindler said on Monday that the low-power technology introduced with the 600MHz mobile Pentium III stacks up well against Transmeta's power-saving technology, called LongRun.

"The numbers showing on Monday ... are in line with [Transmeta's] stated claims," Spindler said.

Not surprisingly, Transmeta did not agree. In a statement issued on Friday, it contested the way Intel measures the power consumption of its processor.

"Intel measures one watt with the processor idle [sleeping] 80 percent of the time. Transmeta's Crusoe chip runs all sorts of Windows and multimedia applications at one watt or less," Transmeta said in the statement.

Recently, Transmeta's Crusoe chip was chosen to operate a jointly branded Internet Appliance (IA) from partners Gateway 2000 and America Online.

Monday's announcement from Intel moves the Santa Clara-based company one step closer to the expected launch of its own branded Internet Appliance (IA), a product that sources close to the company have said will arrive by the end of this year.

The first Intel IA offering, a device with an integrated phone receiver and 14-inch CRT screen will run a version of the Linux operating system, according to one source.

The use of the Crusoe processor and Intel's new low-power PIIIs, both mobile PC processors, in desktop IAs, stems from the ability of these low-watt processors to optimise the Web browsing experience. According to one source within Intel, internet content is increasingly geared toward mobile and handheld device browsing.

"There are some advantages to browser technology for which these [processors] could be applied to Internet Appliances," Spindler agreed.

Spindler also said that Intel will embrace the Linux community to develop applications for the low-power space, in the same manner it has opened its IA-64 code to Linux developers to create applications for the next generation, 64-bit operating environment.

"The Unix-based operating systems don't have the power-friendly features built into them," Spindler said.

Low-watt power requirements for the new Intel processors are based solely on the power needs of the processor, and not the overall system requirements of any particular product, that when totaled, can run as high as 15.8 watts overall power drain, depending on manufacturer configuration, Spindler added.

Pricing for Intel's new processors ranges from $134 for the low-power 500MHz Celeron, to $US562 for the 750MHz mobile Pentium III, in 1,000-unit quantities.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
