Intel unveiled on Tuesday a new aspect of its upcoming microprocessor architecture, which promises better power management and efficiency.
Speaking in the afternoon keynote on day one of the Intel Developer Forum (IDF) in San Francisco, Pat Gelsinger, Intel's senior vice president and general manager of the digital enterprise group, showcased Nehalem EX for the expandable server market, consisting of eight-core processors on a single die. He then announced a power-gate feature incorporating a "turbo mode"--a "previously undiscussed" element--for the Nehalem family of processors.

With the turbo mode, in a situation where not all the cores are necessary for a particular workload, the ones that are idle will be turned off and power is channeled to the cores that are active, making them more efficient.
