(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) - 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.
