Barcelona: AMD Unveils New Power Metric for CPUs
629397
Throughout the past five years, AMD has stated Intel has been unfair in the way it measures its CPUs' power consumption, and presents those numbers to the public. But it hasn't come up with an alternative method...until today. Beginning with the Barcelona generation of quad-core CPUs, AMD will utilize what it calls average CPU power (ACP), which unlike Thermal Design Point (TDP) is not based on how much power is required to cool a chip, but rather to run it.

With Christmas just 11 days away, you have to wonder what Hector Ruiz is going to find under his tree. It&#8217;s been a terrible year for Advanced Micro Devices, and the chipmaker&#8217;s analysts conference on Thursday did nothing to spread holiday cheer.Confirming what many in the chip world had suspected for some time, CEO Ruiz and other AMD execs fessed up that bugs in its new quad-core Barcelona server and Phenom desktop chips will&#160;delay these key next-generation technologies.The technical problems will delay general availability of the fastest version of the chips for three or four months. Customers willing to settle for slower clock speeds will be able to get the processors sooner; for example, AMD will ship a 2 gigahertz version of the Barcelona first, instead of the expected 2.5 gigahertz speed. In either case, the chips will be close to a year late; the original target date was the first quarter of 2007.AMD STUMBLES AS INTEL SPEEDS AHEADThe problem couldn&#8217;t come at a worse time. AMD has struggled all year to close the performance gap between its high-end chips and Intel&#8217;s. Barcelona, the company had promised, would restore its technical supremacy. Indeed some analysts said they had expected the quad-core server chip to do just that. &#8220;At 2.5 gigahertz it would have beaten any Intel products,&#8221; said analyst Nathan Brookwood of Insight64. &#8220;But at 2 gigahertz, it&#8217;s bringing up the rear,&#8221; he said.Intel, meanwhile, has corrected many of the problems that dogged it earlier in the decade. &#8220;AMD isn&#8217;t competing against the Intel of two years ago,&#8221; said Dean McCarron of Mercury Research. Intel has had quad-core chips in the market for about a year. To be fair, its chips are based on a somewhat simpler design; Intel gets to four cores by packaging two dual-core chips together. By contrast, AMD&#8217;s design integrates four cores on one chip, a more efficient solution, said McCarron. Except that AMD&#8217;s approach reduces yields and thus raises manufacturing costs, he added.There was earlier speculation that Barcelona&#8217;s problems were related to the ATI graphics chipset, but the problem turns out to be deeper, at the chip level. AMD has said it is related to the translation lookaside buffer (TLB) in the processor&#39;s L3 cache.DOUBTS ABOUT A QUICK FIXIn the Thursday conference, analysts had expected discussion of the company&#8217;s &#8220;asset light strategy,&#8221; which will apparently entail outsourcing more manufacturing to foundries such as Chartered Semiconductor or TSMC. But they didn&#8217;t get it, and the lack of details made CEO Ruiz&#8217;s promise to return to profitability in 2008 less credible to Wall Street. AMD&#8217;s financial performance has been terrible, losing money for four straight quarters. Part of the reason: Intel and AMD have engaged in a bloody price war, a struggle that has been very tough on the smaller company&#8217;s profit margins. But the Barcelona and Phenom delays are serious self-inflicted wounds.AMD&#8217;s stock lost another few points yesterday and has now shed about 40% in the last two months and a bone-jarring 56% since the beginning of the year. At $8.84 a share, Thursday&#8217;s closing price, the stock is at its lowest ebb since the summer of 2003. Ironically, AMD has so far&#160;rewarded Ruiz with pay raises.

(InfoWorld) - Advanced Micro Devices (AMD) has pumped up the performance of its Athlon 64 X2 dual-core processor and cooled down two single-core Athlon 64 processors. The top-of-the-range AMD Athlon 64 X2 dual-core processor is now the 6000+, with a clock speed of 3GHz and 2MB of L2 cache. It sells for $464 in quantities of 1,000 or more. The previous fastest model, the 5600+ with a clock speed of 2.8GHz, now sells for $326 in quantities of 1,000 or more. With its high-performance dual-core systems, AMD hopes to profit from the introduction of Microsoft's new operating system Windows Vista, which places greater demands on computing hardware. There's no speed boost for the single-core Athlon 64 processor, but AMD is now manufacturing the 3500+ and 3800+ models using a 65-nanometer production process, reducing the chips' die-size and energy consumption while offering the same computing performance. The latest versions consume 45 watts, compared to 62 watts for the previous generation, in which the smallest features etched on the chips had a spacing of 90nm. The 3500+ sells for $88 in quantities of 1,000 or more, and the 3800+ for $93. The faster dual-core chips will appeal primarily to gaming enthusiasts, and will appear shortly in PCs from Alienware and Voodoo, the gaming PC divisions of Dell and Hewlett-Packard, respectively, said AMD. Fujitsu Siemens Computers (Holding) will use the lower-power processors in its Esprimo enterprise desktop range, which it promotes as an energy-efficient range, the company said. Two weeks ago, AMDÂ introduced new dual-core Opteron processorsÂ for servers that are either faster or consume less power than previous chips. While AMD had begun to pull ahead in the market for low-power server and desktop chips, IntelÂ is fighting back. Last month,Â Intel persuaded Sun MicrosystemsÂ to use its Xeon processors in future servers and workstations based on the x86 architecture. Sun had only used AMD chips in those machines in recent years, and will now use chips from both manufacturers. At the top of the scale, Intel took the lead in the market for quad-core server chips last November, with the launch of its Xeon 5300 series, previously known as Clovertown. AMD won't introduce its range of energy-efficient quad-core server processors, code-named Barcelona, until the middle of this year.

(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.

(InfoWorld) - Advanced Micro Devices (AMD) showed a laboratory version of its promised "Barcelona" quad-core Opteron 8000 server chip to analysts on Thursday, saying it planned to begin selling the product in the second quarter of 2007. AMDÂ will pitch the chip to users of high-end, commercial workstations and servers, who could see performance improvements of up to 70 percent in database applications and 40 percent in floating-point applications compared to AMD's dual-core "Rev F" Opteron. The demonstration Thursday, to analysts gathered in Berkeley, California, was AMD's second effort to show that it is keeping up with quad-core chips from rival Intel Corp. AMD also launched its "4x4" Quad FX Platform, a motherboard with two dual-core Athlon 64 FX-70 series chips intended for the desktop gaming market. Intel lost significant market share to AMD in 2006Â as it was criticized for being slow to produce chips that emphasized power efficiency instead of pure calculating speed. Intel hasÂ bounced back in recent monthsÂ with the launch of dual-core chips including the Core 2 Duo for desktops and Xeon 5100 "Woodcrest" for servers. On Nov. 14 Intel reached the market first with quad-core chips, with the Core 2 Extreme QX6700 for gamers and Xeon 5300 for servers. Intel has alsoÂ led the industry in converting its chip designsÂ from the 90-nanometer process to 65 nm, including all four processors mentioned above. In response, AMD has criticized Intel's quad-core design as merely gluing two dual-core Woodcrest chips together, whereas the Barcelona chip includes all four cores on a single piece of silicon. Analysts are divided on the impact of that distinction, and say they cannot measure the difference until they compare benchmarks from both finished versions. Still, AMD trumpeted Barcelona as an engineering achievement that marks the company's shift to 65-nm architecture. By shrinking the processor die, AMD is able to improve power efficiency and squeeze an extra level of shared cache memory onto the design, said John Fruehe, AMD's worldwide market development manager for server and workstation products. "As you add more cores, it becomes less about brute force and more about the efficiency of how many things you can do at once, and how efficiently you can order them," he said. "From a customer perspective, those who will see the biggest bang for their buck with quad-core are people running applications like larger databases. The more threaded an application is, the more benefit you get." The users who will see the greatest return on their quad-core investment are users of multithreaded applications like CRM (customer relationship management), ERP (enterprise resource planning), e-commerce and virtualization, Fruehe said. AMD will first launch the Barcelona design on a four-socket board (running four quad-core chips) and a two-socket board (running two quad-core chips). The company will wait until later in 2007 to launch single-socket Barcelona boards, which are used mainly to develop new applications for the larger servers or to run Web farms to handle multiple simultaneous processing requests. AMD expects servers vendors such as Dell Inc., Hewlett-Packard Co., IBM Corp. and Sun Microsystems Inc. to adopt the new technology for their servers in 2007, although none of those companies has yet made a public announcement.
