Do I need to turn on turbo mode for performance?

The "Turbo mode" function is based on Nehalem's "Integrated Power Gate" power management technology, which allows to shut down some cores and add power to other cores, allowing them to operate more efficiently. Running at a high frequency, the TDP of the entire CPU remains unchanged.                                                                                                                                                               (Recommended learning: phpstorm)

Do you still remember the "turbo" key on the 486 and 586 computers before?

Maybe you have used it too. The incompetent "acceleration" function in the past was actually designed to prevent the program from executing too fast. If you turn it on, the CPU will run in normal mode. If you turn it off, the CPU speed will decrease.

Core i7 (development code: Nehalem) and the upcoming Core i5 (not supported by the i3 series) will support "Turbo Mode", but you can rest assured that this feature is completely different from before.

We can take computer games as an example. You use a Core i7 4-core processor, but the game only uses 1 core. Generally speaking, the other three cores are idle, and you can only get 4-core processing. 1/4 of the performance of the processor.

But Core i7 will turn off the other three cores at this time to reduce the power consumption and heat generation of the CPU, and then overclock the core that actually works to obtain higher performance. At this stage, there is news that a A 3.0GHz core will automatically boost to 3.2GHz or even 3.4GHz.

Indeed, This technology can optimize the usage efficiency of the CPU and is expected to change the view that "multi-core processing is not as good as high-frequency dual-core processors", but some people have also suggested that "Turbo Mode" will make manual overclocking more difficult. Complex, because if the CPU has been pre-overclocked, turning on "Turbo Mode" is very dangerous.
