Intel Intel unveiled a power gate feature incorporating a "turbo" mode for its upcoming 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. Intel also showcased the Nehalem-EX for the expandable server market, which consists of eight-core processors on a single die.

Except (and I admit I didn't read the article) it sounds like they're boosting the performance on the remaining cores by channeling the power from the ones that are disabled (i.e., boosting single-threaded processing slightly while using the same amount of total power?)

Correct. For example, in a 6x 1.6 GHz CPU, they could turn off 4 of the cores, use some of the saved power to overclock the remaining two cores to 1.8 or 2.0 GHz, and get faster performance with less overall power usage.
