(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.

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.
