Notebooks' next phase

The talk of Intel's Developers Forum being held this week will no doubt revolve around the chipmaker's soon to be released chipset code-named Banias. Although it remains unknown exactly how much the world's largest semiconductor manufacturer intends to reveal about the long-awaited technology, one thing is for certain: it stands to raise some interesting questions about the future of mobile computing.

For a start, it's said to be a brand new architecture completely developed from the ground up to address the central problems facing mobile processing. Namely, the amount of power needed by a notebook's central processing unit (CPU) and the subsequent heat this generates. Power consumption also has an inverse relationship with battery life in that the more power used, the less mobile time users have from the battery like Hp Pavilion dv9000 battery(Hp dv9000 battery), Hp EV087AA battery, Hp EX942AA battery, Hp Pavilion ZT3000 battery, Hp 337607-001 battery, Hp 337607-003 battery, Hp PB992A battery, Hp PB994A battery, Hp PB991A battery.

To date, reports on Intel's Banias chipset have been conflicting and Intel has been keeping mum about what's been made available in terms of specifications, clock speeds and architecture. However, the manufacturer has revealed the chipset will run at a slower clock speed and therefore will require less power and generate less heat, yet at the same time it will match the performance of its current flagship mobile Pentium 4 processors.

According to industry sources, it is assumed that the first Banias chip will have a clock speed of 1.4GHz but have the processing equivalence of Intel's 2.2GHz P4.

It's a significant step for Intel, considering the company has spent years convincing the market that clock speed is the defining factor of a processor's performance. Now the biggest challenge will be selling to the world the concept that more megahertz doesn't necessarily mean more power.

Laurie White, Toshiba's product marketing manager, information systems division, doesn't see this as being a major stumbling block. He argues that Intel might not face such a big challenge after all, as Banias will be targeted at SME companies and corporate users, which are traditionally more educated than the majority of retail customers.

"It's actually extremely easy for Intel because they aren't targeting home users," he says.

As for rival chipmaker AMD, the company is touting Intel's reversal as a vindication of its long-held beliefs. "We fully support the statement that megahertz isn't the telling benchmark of a chip's performance," says John Robinson, managing director of AMD Australia/NZ.

To use a motoring analogy, clock speed is equated to revolutions per minute, and just because a car engine might rev at 8,000 RPMs doesn't necessarily mean it's more powerful than an engine revving at 5,000 RPMs.

"Unfortunately there is the perception that clock speed is the be-all and end-all," says Robinson.

Instead, performance is relative to the amount of work done during each cycle plus the cycle speed. But it's not an easy metric to agree on, according to most industry pundits, as there are too many vested interests by manufacturers to come up with an industry standard and easily recognisable benchmark.

AMD's roadmap will see the chipmaker move to 64-bit technology in the first half of next year. Initially for desktops, Robinson claims AMD will have notebook versions of its Claw Hammer 64-bit processors by the end of the first quarter or the beginning of the second quarter next year.
