Here it is in print: Neomagic STILL has a power advantage of 1/2 watt compared to 2 watts for Intels expected introduction in mid 1998, due to it's embedded design. Toshiba is scratching their heads figuring out how to quell power hungry designs. ""Intel took steps toward that end last week when it formally introduced its 200- and 233-MHz Tillamook processors, consuming 3.4 and 3.9 W, respectively. By contrast, Intel's fastest Pentium 166-MHz processor for notebooks takes 7.7 W. "We've given back three or four watts to the notebook designers, so they can build higher-performance systems or extend the battery life by an hour," said Stephen Nachtsheim, vice president of the mobile group. Yet some OEMs said Tillamook is just a respite in the power battle. Indeed, power consumption will likely jump closer to Intel's self-imposed 8.0-W ceiling when the company unveils its 0.25-micron Pentium II for mobile systems, Intel acknowledged. On top of that, Intel plans to introduce the Accelerated Graphics Port (AGP) for notebooks starting in mid-1998. Some OEMs said that the dedicated graphics bus will add another 2 W to the equation, leaving precious few remaining watts within the 20-odd watt power ceiling for notebooks. "When we look at the AGP and Pentium II, then I have to say I don't know how we are going to handle that huge power consumption," said a notebook manager for Toshiba Corp.(( easy::: use Neomagic 128XD...DUH !!!!)) "The thermal environment is the No. 1 priority for my design team," said Arif Maskatia, vice president of the mobile-systems advanced-technology group for Acer Advanced Labs Inc. (San Jose, Calif.). "In the past, most power consumption used to be from the LCD. Now it's the processor." While Intel is holding fast to its 8.0-W processor allotment, it is beginning to take a hard look at other components it considers power hogs--notably, the graphics subsystem. "As we move toward faster front-side [processor] buses and AGP technology, there's a real concern that left unchecked you can take existing budgets and go up by a factor of 10," said Intel's Antone. He said the company will share with other chip vendors ways to reduce power consumption by splitting cores and throttling clocks. The emphasis could encourage more vendors to embrace less power-hungry graphics, such as embedded frame-buffer memories like those from NeoMagic Corp. (Santa Clara), which consume about half a watt. ( GO NEOMAGIC RAH RAH RAH !!!!) On the software front, the Intel Power Monitor measures an application's power consumption and allows developers to fine-tune their software. "It gives them a tool to see whether they're revving their engine when they're not doing anything," Antone said. Unlike other industry specs, particularly those imposed by Microsoft, Intel's new guidelines are not mandatory; (( INTERPRETATION ....INTEL WILL NOT CHANCE DESIGNING THEMSELVES OUT OF THE MARKET WITH PROPRIETORY DESIGNS AGAINST CURRENT STANDARDS )) Intel will not try to enforce adherence by certification. "We have not comprehended any kind of seal of approval or validation process," Antone said. "This is meant to be a means to laying out guidelines."
