Turbo Boost: Automatic Overclocking
The new Core i7 800-series CPUs and the Core i5 750 still support the same automatic overclocking functionality, or Turbo Boost, as the Core i7 900-series processors. However, this feature has been jacked up on the newer chips. Core i7 900-series CPUs will only increase their multipliers to a maximum of two additional steps according to system demands (effectively taking a 3.33-GHz processor to 3.6-GHz depending on how many cores are in use). The new Lynnfield processors are able to jump up five multiplier steps for the 800-series chips (taking a 2.93-GHz processor to 3.6-GHz) and four for the Core i5 750 (2.66-GHz to a maximum 3.2-GHz).
