AMD Building K7 Platform To Rival Intel
techweb.com
As Advanced Micro Devices' K7 moves closer to a scheduled rollout sometime in June, both AMD and chip set makers are working together to establish an infrastructure of supporting logic.
According to executives at chip set maker Via Technologies, AMD will develop and ship a small number of high-endcore logic chip sets for systems that use two or more K7s running in parallel. Via, meanwhile, will design and supply single-processor chip sets for the higher-volume, "value-oriented" mass market, according to Dean Hays, director of marketing for Via's U.S. operations in Fremont, Calif.
Likewise, Acer Laboratories will also focus on uniprocessor K7 chip sets. "It probably won't be in the multiprocessor market, since our focus is on the mainstream, high-volume market," said Nancy Hartsoch, vice-president of sales and marketing for Acer, in San Jose, Calif.
The K7's EV-6 bus, which AMD licensed from Digital Equipment, is fundamentally different than either the Super7 or P6 bus that Pentium-class and Pentium II-class processors use. By selecting a unique microprocessor and bus architecture, AMD has committed itself towards designing a true alternative to Intel's chips.
"We're migrating from a microprocessor company to a [computing] platform company," said a spokesman for AMD, in Sunnyvale, Calif.
That has forced AMD to take its relationship with its chip set suppliers to a new level. When Intel abandoned the Socket 7 Pentium market for the Pentium II microprocessor and its Slot 1 connector, only Via, Acer, and Silicon Integrated Systems (SiS), plus some much smaller chip set companies, were left to provide core logic for AMD's K6 and its successors. Intel, meanwhile, held onto its P6 patent technology with a tight grip, only recently licensing Via, SiS, and S3 to use the bus. Acer is still negotiating a license.
Had suppliers like Via been recruited by Intel to produce the Slot 1 chip sets, AMD would have been left in a very precarious position, said Via's Hays. But sticking with AMD has paid off for all parties. As AMD's microprocessor market share has grown, so has revenue for the supporting logic. Offered the opportunity to manufacture a K7 chip set, Hays said Via enthusiastically agreed. A day later, three AMD engineers showed up at Hays' doorstep in Fremont, ready to begin work.
Although the two companies have worked closely together since then, Hays estimated that Via's ability to ship a K7 chipset would be about a month behind AMD. Acer Labs will also ship a K7 chip set later in 1999, Hartsoch said.
An AMD representative declined to comment on specific details concerning the company's chip set plans or its relationships with its partners. Online computer-hardware review sites, however, have noted the existence of the AMD-751, AMD-752, AMD-755, and AMD-756, two unreleased K7 chip sets each with a north and south bridge. AMD originally posted the chip sets to its website to display their year 2000 compliance, then later removed them. However, an AMD spokesman confirmed all four chip sets as AMD products designed for the K7.
The EV-6 bus runs at 200 MHz, twice as fast as both the 100-MHz "Super7" bus used in Socket 7 systems and Intel's own 100-MHz P6 bus. With the delayed release of the "Camino" or Intel 820 chip set in September, Intel will probably increase the P6 bus speed to 133 MHz.
Hays said there was no technical reason why the Super7 bus could not be increased to 133 MHz. But AMD's engineers have been restricted to improving its K6-III and finalizing the K7, Hays said, and the two sides have not met to hammer out a design specification. AMD's K7 will be released at 500-, 550, and 600-MHz, according to an AMD spokesman, although industry sources close to AMD added that only limited quantities of the 500-MHz speed grade would be manufactured.
AMD has not publicly made any overtures to license the EV-6 bus as a true alternative to Intel's P6 technology. The EV-6 patents are also still legally owned by Compaq Computer, which acquired Digital. But Hays said he hopes that AMD can begin delivering on its promise to deliver a competitive platform as well as a competitive processor.
"I think it would be wonderful to shift the whole [Super7] infrastructure to something the market could rally around," Hays said. |
