To begin to understand what the Turbo Boost, you must at least briefly to imagine what the "acceleration" of computer components.
Acceleration (or overclocking) computer - is to increase its speed through the exploitation of components in non-standard modes (usually at a higher frequency).The most common type of overclocking is to increase the frequency of the CPU and GPU, and RAM and video memory.
Overclocking the phenomenon has existed since the beginning of the 90s of the last century, after the CPU 486 series, the notion of a factor.Motherboard manufacturers wanting to standardize its entire line of products under the new processors from Intel, designed their products in such a way that by closing certain jumpers on the "mother" you can set the frequency of the bus and the multiplier used by the processor.A final CPU frequency - this is the product of the frequency of the bus by a factor.
Over time, thanks to the efforts of some companies (Abit, Epox and some others), acceleration has ceased to be the lot of a separate caste of computer guru.In the BIOS of most motherboards there were whole sections of settings that allow even inexperienced users to change parameters such as the frequency of the processor bus, the voltage supplied to the CPU, the timings (delay) of the memory, etc.
Drinking overclocking processors from different manufacturers were also different.In AMD, for example, if not encouraged, then, in any case, do not put a spoke in the wheel.In addition, the processor of this firm for the first time in many years there was a factor, unlocked "up", ieallowing to raise the CPU frequency higher than the nominal.But Intel has long been a consistent opponent of acceleration.For example, motherboards sold under its brand name does not have any options, responsible for fine-tuning the parameters of the processor and memory.Things began to change in late 2008, when the new processors Bloomfield appeared technology Turbo Boost.
The cause of the Turbo Boost is a multi-core processors today.Although the first dual-core desktop processors are over almost seven years, it is still not all applications are optimized for multi-threading.In this regard, the situation often arises when one or two cores are loaded by almost 100%, and the rest is in the "rest".In this situation, the new processors are getting minimal advantage over their single-core predecessors.A Turbo Boost automatically for some time to raise the frequency of the cores loaded, thereby increasing and the real and apparent speed of the processor in a given task.This automation does not go beyond the processor TDP assigned to it by the manufacturer.In other words, the processor in such a non-standard mode will not produce heat more than able to take from it the nominal cooling system.
Now Turbo Boost technology supports most Intel processor family Core i (but not all!).Budget Pentium, and Celeron it is unfortunately deprived.Each model of processor along with a nominal frequency and a maximum "acceleration" frequency.For example, the Intel Core i7 processor 870 at a nominal frequency of 2.93 GHz in Turbo Boost mode may accelerate to 3.6 GHz quite impressive.
Those who do not know how to turn on Turbo Boost, can reassure default this option is included in modern BIOSes (unless, of course, installed in the computer processor supports it).As a rule, the menu item is responsible for the operation of this technology, called or «Turbo Boost», or «Turbo mode», or something very similar.The advanced firmware designed for experienced users may not only turn on / off this mode (parameter Enable / Disable), and the regulation of the maximum multiplier for each core.Sometimes, even the increase in the maximum permitted teplopaketa processor.The latter function allows the CPU to operate in turbo mode for a longer time or at the same time maintain the increased frequency on more cores.
also necessary to establish a system of Turbo Boost Technology Driver, allows modern operating systems to ensure correct their interaction with the motherboard BIOS.
Recently, AMD has in some generations of its processors using analogue technology turbo boost - TurboCore.From Intel's technology it is anything other than the name, in fact, no different.
