Is CPU overclocking same as CPU frequency in turbo mode?
Everyone knows about CPU overclocking, but what about CPU frequency in Turbo mode? Maybe you will also see this parameter logo when buying a processor, so overclocking is a turbo frequency? What is acceleration? What is turbo frequency? What is difference between overclocking and turbo speed? There are many questions, so with these questions today I will introduce you to processor overclocking and turbo frequency.
What is overclocking?
Overclocking is act of increasing operating frequency of CPU, graphics card, memory, and other components by human action so that they can operate at a higher frequency to increase overall performance of computer. Overclocking in English is called "Over Clock" and is a technical means of increasing main frequency of chip by adjusting hardware settings to obtain performance that exceeds nominal frequency.
For example, an AMD Phenom II X4 955 black box processor rated at 3.2GHz can be overclocked to 4GHz using software called overclocking.
The performance improvement caused by CPU overclocking is most obvious, because CPU is a very complex product, so actually manufacturer does not have ability to control frequency at which CPU can run stably, only through continuous testing Get frequency range that can run stably. then note nominal frequency, and then set aside a certain number of spare frequencies, so for users to discover or use these spare frequencies, they can use overclocking.
What is turbo frequency?
Rui can be said to be wise, that is, intelligent, turbo frequency does not require human intervention, turbo frequency technology means that when CPU is processing complex tasks, it will automatically increase operating frequency to maximize its own performance. solve various complex problems.
To put it simply, turbo frequency means that after program starts, processor will automatically overclock to appropriate frequency, for example, a processor with a nominal frequency of 3 GHz and a turbo frequency of 3.5 GHz. 1GHz will be used, but when you run a big game, it can go up to 3.5GHz, in other words, turbo is a temporary overclock.
Then you will definitely think, why throw it back? In fact, main reason is to take into account energy consumption and heat dissipation.
So let's summarize their differences:
Turbo frequency: The CPU dynamically increases processor's operating frequency to increase processor's performance according to needs of actual running program, while keeping processor stable within specified power consumption, current, voltage. and temperature range. If processor fails, it is covered by warranty. The turbo frequency is automatically realized by CPU without manual adjustments, and CPU runs stably.
Overclocking: The user forces all CPU cores to run at a frequency higher than nominal frequency. Power consumption, current, voltage and temperature may be outside specified limits. In event of damage, warranty will not apply. . Overclocking requires adjusting various parameters such as voltage, heat dissipation, FSB, power supply, BIOS, etc., and this is fraught with instability of system.
