(InfoWorld) - Intel has been beating out a steady rhythm of big product announcements in recent months. And last week that beat went on: The company shipped Merom, the mobile entry in Intelâs 64-bit Core 2 Duo processor line. The announcement, following on the heels of the delivery in May of AMDâs dual-core Turion 64-bit notebook CPUs, shows Intel coming on hard and fast to regain some of the market share it has lost. Still, with so many products flowing out of the pipeline at the same time, Intel will have to be careful not to cannibalize its own efforts. Merom is a mobile entry in Intelâs 64-bit Core 2 Duo processor line, as well as Intelâs answer to the Turion CPUs. Intelâs new Core 2 Duo T7200, T7400, and T7600 notebook CPUs clock in at 2GHz, 2.16GHz, and 2.33GHz, respectively, with 4GB of shared cache and the same Intel 945 Express family chip sets as the 32-bit Core Solo and Core Duos that preceded them. Consumers will most likely see Merom sold as Centrino Duo, an adaptation of the long-running and megapopular Intel brand that bundles CPU, chip set, graphics, and wireless networking controller. And thatâs where the problem lies. Centrino has been a home run for Intel in the notebook space, but the decision to throw the Centrino brand onto yet another product line is bound to have consumers and salespeople scratching their heads as they try to grasp the differences between no fewer than three different âCentrinosâ on the market. For example, Core Duo has been a surprise hit among Intel notebook OEMs, perhaps because Apple has done so well with its Core Duo MacBook Pro line. That puts Intel in the position of having two dual-core notebook CPUs that use the same chip set, with very similar claims with regard to power efficiency and performance. That could leave consumers to choose between two flavors of Intel dual-core notebooks: Centrino Duo and Merom Centrino Duo. Centrino Duo, a 64-bit technology in a market where 32-bit software predominates, might slow adoption of the Merom Centrino Duo platform. Uptake may be even slower if Core Duo notebooks are less expensive than those built with Merom. So read those labels carefully!ADVERTISEMENTMAKE SOA REAL WITH IBM WEBSPHERE PODCASTStreamline processes and maximize efficiency within a proven service oriented architecture.

(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) - What will they put in notebook PCs next? At Intel's recent Developer Forum conference in Beijing, the company revealed it's working on quad-core processing to go. Set for release in 2008, the quad-core mobile processor is aimed at high-level gaming and mobile computers, where users will trade battery life for more performance. While the most demanding users (including gamers and those doing video editing) always want more processing power, this chip won't appear in standard business notebooks for some time. "You'll see it at the high end, but I don't see it running so fast into the mainstream because I don't believe there will be enough threaded applications that will justify the trade-offs," says Mooly Eden, vice president and general manager of Intel's mobile platform group. (Multithreaded applications allow several parts of software code to be executed simultaneously, taking advantage of multiple processing cores.) The quad-core mobile chip will likely differ in some way from Intel's current desktop and server quad-core chips, which strap together two dual-core dies inside a single-chip package. Meanwhile, the next version of Intel's Centrino notebook platform, code-named Santa Rosa, hit the market last month. Compared with Centrino, Santa Rosa offers several improvements, including dynamic acceleration, which raises the clock speed of one processor core above the guaranteed frequency level when the other core has powered down. This raises the performance of the remaining core while keeping the processor operating within the thermal limits envisioned by Intel engineers. This differentiates Dynamic Acceleration from overclocking, where users raise the frequency of a processor beyond the intended level.ADVERTISEMENTIBM Information On Demand 2006Industrial Industry Leaders, please join us at IBM's premier information management global event, IBM Information On Demand 2006, October 15-20, Anaheim, CA.
