Intel Offers Details Of Core Successor 'Nehalem'
Intel (NSDQ: INTC) on Tuesday released details of its new series of microprocessors (code-named Nehalem) which will replace the existing Core microarchitecture family and is scheduled to start shipping in the fourth quarter.
Patrick Gelsinger, senior VP and general manager for Intel's Digital Enterprise Group, made several technical disclosures for Nehalem during his keynote at the Intel Developer Forum in San Francisco, which runs through Thursday. Among the key details was power management technology that would start with Nehalem and continue in future generations of processors.
"Turbo mode" incorporates new "power-gates" technology from Intel that can turn individual cores on or off, depending on the workload demand. As a result, in a four-core Nehalem processor, for example, two cores could be shutdown if only two are needed for a given task. This boosts overall power to performance ratios.
