(InfoWorld) - AMD on Monday is giving the public an advanced look at how its pending quad-core chip will improve performance and save energy. AMD, playing catch-up to rival Intel, whoseÂ quad-core XeonÂ product launched in 2006, will discuss features of its quad-core product, code-named Barcelona, at the International Solid States Circuits Conference in San Francisco, a forum for engineers in solid state circuitry and system-on-a-chip processor design. AMD says it will present details at the conference of how Barcelona, due to be released in mid-2007, improves performance and energy efficiency over the competition and over its own dual-core processor, the Opteron, which it introduced in 2003. Barcelona will feature "Enhanced PowerNow" technology, which will dynamically adjust core frequencies as workloads change in order to power down cores when not needed to save energy, said Brent Kerby, product marketing manager for Opteron. Under the PowerNow technology already deployed in the dual-core Opteron, the OS delivers the needed power to the busiest core, but if the other core is not as busy, it will still receive the voltage demanded of the busiest core, Kerby said. But with Enhanced PowerNow, while the busiest core will receive the power it needs, the OS will reduce the frequency and voltage of the remaining cores because they aren't as busy. "We still see power savings with our current PowerNow technology, but it's going to get better with Barcelona because we're going to be able to dynamically and independently adjust the core frequencies of each individual core," he said. Also in Barcelona, the OS will directly communicate with the CPU instead of first going through the CPU driver, a more efficient approach, he said. "With Barcelona, there is no CPU driver middleman. The OS can tell the processor directly, 'Hey this is how much work I'm doing,' and the Barcelona core will determine when the best time is to make that change. It's not doing it blindly," he said. Barcelona also separates the power management of the cores from that of the memory controller, which is embedded in AMD-designed processors. That way, frequency and voltage can be reduced to the cores when they are not busy and increased to the memory controller when it is busy, and vice versa. AMD claims an 80 percent reduction in memory controller power usage with this design change. Barcelona will also feature enhanced clock-gating, which means core logic circuits can be turned on or off to save power. Like settings on a coffee grinder, the chip can do "coarse" or "fine" clock gating, shutting down increasingly finer sections of core logic as needed. AMD claims that Barcelona can deliver a 40 percent improvement in performance over "the competition." While not mentioning Intel's Xeon specifically, AMD has long pointed out that its quad-core chip will be four cores designed on the same piece of silicon, while Intel's design is two dual-core processors packaged together.

(InfoWorld) - After watching its market share for the North American desktop PC market slip in a soft third quarter, Advanced Micro Devices Inc. (AMD) will seek greater profits in 2007 throughÂ a new family of quad-core server chipsÂ and itsÂ acquisition of graphics chip maker ATI. "From a customer perspective, our integration is completed," said Henri Richard, AMD's chief sales and marketing officer during the company's annual analyst meeting in New York on Thursday. The companies still face several years of work to reach their goal of launching a combined processor and graphics chip called Fusion, but since closing the deal in October, they have already combined sales forces, supply chains and manufacturing facilities. In the short term, that will enable "the new AMD" to benefit whenÂ Microsoft's launch of the Windows VistaÂ OS sparks increased demand for visual capability in PCs. "Vista will change the paradigm of how people relate to their PCs and their criteria for selecting devices in 2007. That emphasis on a more visual experience will give AMD an edge," Richard said. AMD will also use the ATI acquisition to enter the fast-growing consumer electronics market in 2007, selling more video processing chips as demand rises for digital and high-definition TV, and selling more embedded chips as handheld devices converge the capabilities of cell phones and PCs, he said. AMD expects 19 percent growth for its chips used in the handheld sector and 44 percent growth in digital TVs. In the meantime, AMD will focus on its bread-and-butter product, the Opteron server chip. AMD plans to increase its revenue from microprocessors and chipsets by 20 percent in 2007, twice its prediction for the industry's growth rate. Chip-making rival Intel Corp. regained some ground in the desktop and server markets in recent months with its Core 2 Duo and dual-core Woodcrest Xeon chips. But AMD is poised to defend its turf. The company demonstrated a four-chip server using laboratory versions of its "Barcelona" quad-core Opteron chip at the meeting. Compared to AMD's own dual-core server chips, the design marks a 40 percent to 70 percent improvement in processing power and a 60 percent improvement in performance per watt. AMD plans to launch that chip for high-end servers in the second half of 2007, and update it with a "Shanghai" model in 2008. The company also plans to expand from its stable of processors designed for two, four and eight-chip servers in 2007 by launching "Budapest,"a quad-core Opteron chip designed for the single-processor servers used in the small business market. AMD will also improve its Turion and Sempron notebook chips, extending battery life with a more efficient "Hawk" model in 2007 and "Griffin" model in 2008. Together, those products will help return AMD to a better mix of products, Richard said. "We had been heavily reliant on the desktop sector. Now our server and laptop segments are growing faster, so we will soon reach the industry average." AMD has already started designing an eight-core server chip, set for release in three years, but has no plans to build chips with even more cores. "I think most people recognize the industry made a mistake getting into the megahertz wars, because we should have been more focused on the efficiency of the overall platform. And we would make another mistake if we got into a core war," said Phil Hester, AMD's chief technology officer. "You'd scratch your head if someone tried to sell you a 16- or 32-cylinder car and ask 'Why on earth do I need this?' You really need something whose capabilities are matched to what you'll use it for every day."

(InfoWorld) - AMD hopes to seize a larger share of the server chip market fromÂ its rival IntelÂ on Monday when it launches the Barcelona quad-core processor. AMD has been shipping the Quad-Core AMD Opteron chip to server vendors throughout August but will use its news conference in San Francisco to publicly announce those partnerships as well as prices and benchmark test results. The company plans to launch a 1.9GHz, 68-watt Barcelona chip that focuses on power efficiency, and a 2.0GHz, 95-watt version that focuses on price/performance, said Randy Allen, AMD's corporate vice president for the server and workstation division. In the fourth quarter, the company will follow that with a 2.3 GHz, 120-watt version for high-performance applications, and higher clock speeds for the first two chips. There is a lot at stake. After launching the original Opteron chip in 2003, the company enjoyed brisk demand as customers applauded the power-efficient performance of that 130-nanometer design process chip. But Intel soon got back in the fight as both companies built smaller, faster components, shrinking their chip scales to 90nm and adding a second core. AMD has endured disappointing results lately,Â posting losses in the hundreds of millions of dollars for recent quartersÂ and focusing its attention onÂ a merger with graphics chip maker ATI. At the same time, Intel claimed bragging rights to beating AMD to quad-core architecture andÂ 65nm scale chips with its ClovertownÂ server chip.Â Intel is also preparing to launch an even smaller-featured design in the fourth quarter with its 45nm Penryn chip. AMD says Barcelona is the answer to the Intel challenge. The chip is designed with all four cores on a single die as opposed to Intel's design of joining two dual-core Woodcrest Xeon chips, Allen said. Even more important, AMD upgraded each core from 64-bit floating point performance to 128-bit and retained its Direct Connect architecture and on-chip memory controller to avoid bottlenecks in data flow, he said. Thanks to that design, the new chip will provide better performance while using the same amount of power, he said. A customer could upgrade a Hewlett-Packard ProLiant DL 385 server from AMD's dual-core to quad-core Opteron and gain faster operation with the same power and cooling demands. "Clovertown will look very anemic, especially as we bring out new frequencies. Customers really don't buy nanometers. What they care about is performance and benchmarking," said Allen. "That Direct Connect architecture is very helpful with virtualization, running multiple OSes, and other applications pulling more data than can be held in on-chip memory." Despite those advantages, AMD has missed out on a spike in market demand driven by a need to upgrade to servers capable of performing virtualization, one analyst said. "A lot of people view this as six months late or more," said Doug Freedman, managing director for research at American Technology Research. "Expectations got ahead of themselves, and some people viewed this as a potential savior for AMD after their server share topped out at the end of last year going up against Intel's dual-die quad-core. Now the feeling is this launch isn't robust enough in terms of samples shipped, design wins, and the complete food chain." To recover, AMD will have to quickly increase its production and release faster versions of Barcelona to improve the chip's availability for a range of applications, Freedman said. Intel executives say they are pressing the lead. "We are very confident, at least on the DP [dual processor] side, that we will have leadership across most of the benchmarks versus Barcelona," said Adesh Gupta, regional platform architecture manager at Intel Asia-Pacific's Server Platforms Group. "There are a small percentage of benchmarks which are floating-point based where we know that they have an advantage and that's an area which we will see them talk about a lot.... If you look at the broader spectrum of applications at the enterprise, we have a significant lead today, and we believe we will have that lead with Clovertown, and once we have Harpertown with 45nm we will extend that lead further," Gupta said. However, some vendors say there is room in the market for both chips. Each processor has its own strengths, said Dell CEO Michael Dell in remarks to financial analysts at the Citigroup Technology Conference in New York on Wednesday. Based on early tests, Dell said, a server using Barcelona chips is faster at running floating-point applications than a computer with Intel's Clovertown chips, but Clovertown is faster than Barcelona at running integer instructions. "So depending on the applications you run, or your theories of computer science, one of those servers may be the best for you. It is simply unacceptable for a company of Dell's size to have only one of those choices," Dell said.
