SAN FRANCISCO (Reuters) - Advanced Micro Devices Inc plans to use technology from Britain's ARM Holdings Plc to make energy-efficient processors for servers, a growing business that the troubled chipmaker hopes will help offset weakness in the struggling PC industry.
AMD will expand its push into the still-new microserver market, combining ARM's architecture typically used in smartphones with the x86 architecture common in PCs and servers, Chief Executive Officer Rory Read said on Monday.
"AMD is the only computing company on the planet that's introducing this ambidextrous architecture spanning both x86 and ARM ecosystems," he told reporters at an event.
One of Silicon Valley's oldest chipmakers, AMD is losing money and struggling to redefine itself as consumers increasingly favor tablets over laptops and as manufacturers worried about the economy hold off on building new PCs.
The company, which is a distant No. 2 to top chipmaker Intel Corp, announced this month it would slash 15 percent of its workforce, while devoting more resources to areas outside of its traditional PC business, including communications, industrial and gaming applications.
AMD's focus on microservers is a clear -- albeit indirect -- bet on the proliferation of smartphones, tablets and other personal computing devices.
"The data center is where we fundamentally think the growth is going to be and where the innovation is going to be," said Lisa Su, AMD's senior vice president and general manager, global business units.
Like Intel, Sunnyvale, California-based AMD was caught flat-footed in recent years with the emergence and fast growth of mobile devices like Apple's iPad.
Nearly all smartphones and tablets now use battery-friendly technology licensed by ARM to chipmakers like Qualcomm and Samsung Electronics.
AMD's adoption of ARM's technology comes as the British company turns toward data centers, where servers using its low-power technology are challenging the powerful Intel processors that currently power most servers. AMD also makes similar x86 server chips.
When it comes to web surfing on tablets, or analyzing activities on Facebook in real time, data centers with many small, efficient processors are more efficient than those with a few large processors, said Patrick Moorhead, the head of Moor Insights & Strategy.
"The new realm of servers is being driven by changes in client devices like smartphones and tablets," Moorhead said. "What mega-data center builders are doing now is trying to find the most optimal architecture, and what they're looking at very closely are microservers."
ARM has been working on its own 64-bit chip technology, a standard suited to data centers that takes better advantage of memory than its 32-bit chip technology used in smartphones and tablets. Intel and AMD already use 64-bit technology in their x86 server processors.
AMD executives said they will focus on 64-bit server chips using ARM technology, with products expected in 2014. They said AMD may eventually use ARM's technology for other kinds of chips as well.
AMD has previously talked about plans to follow a strategy of adding other companies' intellectual property to its future chip designs, mixing and matching different technologies to suit customers' needs.
Read, who left PC maker Lenovo last year to lead AMD, told analysts on a recent quarterly conference call that he had underestimated how quickly the PC industry was changing. He said AMD had to speed up its transformation.
AMD expects its revenue to fall 10 percent in the current quarter compared with the September quarter. Reflecting the chipmaker's troubles, AMD's stock has fallen 59 percent over the past year.
AMD took a step into the microserver market in March with the acquisition of Silicon Valley startup SeaMicro for $334 million, But it is not the only company to bet on microservers.
Austin, Texas-based startup Calxeda is also focusing on ARM-based processors for data centers and Intel is working on low-powered versions of its x86 chips.
Dell and Hewlett-Packard have also said they plan to sell ARM-based servers.
With years of execution setbacks also weighing on AMD, the company is burning through cash, and industry analysts have recently become concerned about future liquidity.
AMD's cash declined $279 million in the third quarter to $1.48 billion. AMD said it was reducing its "optimal" cash target to $1.1 million from $1.5 billion due to the business' now smaller size.
In June, AMD announced it would add security technology designed by ARM to its processors, fueling speculation the two companies might be moving toward a deeper relationship.
