To begin with, to understand what Turbo Boost is, you need to at least briefly imagine what “overclocking" of computer components is.
Acceleration (or overclocking) of a computer is an increase in its speed by operating components in abnormal modes (usually at an increased frequency). The most common type of overclocking is to increase the frequency of the central and graphic processors, as well as operational and video memory.
Overclocking of the processor as a phenomenon has existed since the beginning of the 90s of the last century, after the concept of the multiplier appeared in the CPU 486th series. Motherboard manufacturers, wanting to unify their products for the entire line of new processors from Intel, designed their products in such a way that by closing individual jumpers to the “mothers” it was possible to set the bus frequency and processor multiplier. And the final frequency of the central processor is the product of the bus frequency by a factor.

Also, the system must be installed Turbo Boost Technology Driver, which allows modern operating systems to ensure their correct interaction with the BIOS of the motherboard.
Recently, AMD has also been using an analogue of turbo boost technology, TurboCore, in some generations of its processors. From technology from Intel, it is nothing but a name, in fact, no different.
