The latest revelation is Turbo Mode. According to IDF stalwart and all round Intel evangelist, Pat Gelsinger, Turbo Mode allows individual cores in its upcoming Core i7 desktop CPU to be entirely switched off.

That in turn allows additional power to be channelled to the remaining cores. The idea is to boost performance in applications that do not make use of all four of Core i7's processor cores.

Intel says that for single threaded applications, the technique allows the speed of a single core to be boosted by two "bins". In layman's terms, a bin translates into around 200-300MHz.
