I'm considering buying a laptop with an i5 at 1.6GHz-2.6GHz. I looked at Intel's page explaining turbo boost, and I have a couple of questions.
One, is this safe for the CPU? It sounds like turbo is essentially overclocking, which would wear the processor out really fast on a laptop. Two, if it IS safe, why doesn't the processor just stay at 2.6 all the time for increased performance? If it has no disadvantage, why wouldn't you just leave it on all the time?

intel and amd turbo boost is a marking ploy..selling point. with newer cpu and gpu there tdp
http://en.wikipedia.org/wiki/Thermal_design_power
all cpu and gpu have this. this is the max temp a cpu or gpu can run at it max speed and max voltage.
what intel and amd does now is tweek the tdp of there product so that they can slow down and use only one core to save power. say all your doing is listing to a mp3. why would yu have a cpu run at max speed and make a lot of heat and kill yur battery. intel and amd says wait a min...lets turn off 3 of the cpu cores and throtttle the last one down. then if yu start playing a game or rendering with your pc and need all of the cpu power it max out to it rated tpd or top turbo boost.

Turbo Boost essentially drops the clock speed of three cores and bumps up the clock on the other core. By doing this, the same amount of heat is put out whilst single threaded applications can take advantage of one better core than 4 slightly worse cores.
