Intel Ends Vicious PC Cycle

While continuing its relentless pursuit of performance, Intel has quietly been developing Transition Management, a technology program to help IT managers cope with constant changes in CPU technologies. Transition Management will stabilise PC designs by keeping platform components such as core logic and memory interfaces consistent through generations of CPUs.

The goal is to upgrade processors without having to re-qualify entire systems, said William A. Swope, vice president of the Intel Architecture Business Group.

"This is a big engineering effort," Swope said. "Designing products for multiple CPU generations is not an easy task." He added that it requires extensive knowledge of new CPUs long before they are introduced and a careful design that will work with multiple clock speeds, multiple interface buses and increasingly fast processors.

The technology, which has been under development for several years, will allow Intel to create chip sets that do not change as the system bus changes. For example, one chip set will accommodate a 66MHz system bus used by Celeron processors or a 100MHz system bus used by Pentium II processors that perform at 350MHz and faster. As Intel transitions to a 133MHz system bus it will be possible to have a single chip set that addresses both 100MHz and 133MHz performance.

For example, the 440BX was designed for several generations of chips, Swope explained. The chip will support the Katmai processor that is slated for introduction early in 1999, and will not be joined by a new chip set design until midyear.

PC vendors are already on board.

"Users like to see motherboards, core logic, BIOS ROMs and other components rarely change," said James McGann, director of product marketing for desktop systems at IBM's Personal Systems Group. "They don't like the churn."

Many PC vendors, such as Dell and Compaq, have already restructured their PC lines in anticipation of Intel's technology. Both offer PC lines that are optimised for this kind of "stability."

Users who have struggled to keep up with Intel's torrid pace are grateful for the change.

Memory technology will be addressed with consistent drivers, according to Swope. He made it clear that Intel has no intention of curtailing development, rather delivering stability for commercial users.

"IS departments want to know there's going to be stability in the systems they buy," said Schelley Olhava, an associate research analyst at International Data Corp.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
