What Is Turbo Boost??

Before the launch of i3, i5, i7 third generation processor Intel and AMD the two

giant players in the world of processor manufacturing are dealing with the idea of multicore processors. The idea of multicore processor is brought up by Intel to enhance the computing speed and performance. As with the current technology has confined the maximum speed which has given rise to multipliers. Now days a common user generally use 4-5 application at a time. So by implementing the idea of multicore the workload is uniformly distributed among them. But problem with this technique is overheating/thermal breakdown. Even a single core generates a lot of heat so we have to invest a lot incase to provide cooling system for all the cores else we have to make a tradeoff between speed and CPU life. The other obstacle to the success of multicore processor is memory management system. As a single memory controller cater the needs of cores by using the same data bus for data transmission so there always exist a state of congestion while executing a heavy task like using a 3D application, floating point calculation, any watching HD multimedia. This would confine the performance to the certain limit and also you have to curb your desires. So for eliminating these problems Intel has launched processor with new feature Turbo Boost. This feature is introduced in the Turbo Boost provides is a feature which you dynamic capability can scale up the clock speed depending within the TDP. With this feature now we have a new generation processor which is flexible enough to provide CPU performance according to the task. We have the Core i5 750 processor which has a base clock speed of 2.66GHz but can scale up to 3.2 GHz, thus provide optimal performance. In the past Intel has provided a feature Dual dynamic acceleration holds the capability to enhance the clock frequency of two cores but Turbo Boost can increase frequency of all cores. The maximum frequency of clock achieved through using Intel Turbo Boost Technology depends on the number of factors which are given as:

Number of active cores at the time of performing task.

Amount of estimated current consumption for desired task.

Amount of estimated power consumption for desired task.

Processor temperature.

How Intel Turbo Boost Works:

Intel Turbo Boost always monitors the power, current usage of a Core i5 or i7 processor and determines its vicinity to the maximum allowable limit i.e. Thermal Design Power (TDP).The Thermal design power is the maximum amount of power a processor is supposed to use under ideal condition. This technology overclock the CPU for a certain period of time when operating system requests for highest ACPI performance The frequency is increased in steps (speed bins), where 1 step is 133 MHz For desktop Intel processor the frequency can be raised by 1-5 steps, or 133- 667 MHz The processor operate in Turbo Boost mode as long as TDP limit is reached when this situation occur then processor reduce the clock speed of active cores by one speed bin.

How to Enable or Disable Intel Turbo Boost Technology on your Computer:

Intel Turbo Boost Technology is enabled by default by a switch in the BIOS where you can either or disable operation. There are no means by which a user can control the operation of Intel Turbo Boost operation. Once enabled Intel Turbo Boost Technology works automatically under operating system for enhancing CPU performance and computer maintenance on high performance applications.

If you are planning to change your computer setup then go for Processor possessing the Turbo Boost Technology and have an extra edge over other.
