An Intel November 2008 white paper [10] discusses "Turbo Boost" technology as a new feature incorporated into Nehalem-based processors released in the same month. [11]A similar feature called Intel Dynamic Acceleration (IDA) was first available with Core 2 Duo, which was based on the Santa Rosa platform and was released on May 10, 2007.
Intel Dynamic Acceleration (IDA) sometimes called Dynamic Acceleration Technology (DAT) is a technology created by Intel Corp. in certain multi-core Intel microprocessors.It increases the clock rate of a single core for every two cores above its base operating frequency if the other cores are idle.

Intel Turbo Boost 2.0 [5] [6] [7] 32 KB data + 32 KB instruction L1 cache and 256 KB L2 cache per core [8] Shared L3 cache which includes the processor graphics ; 64-byte cache line size; New μOP cache, up to 1536-entry; Improved 3 integer ALU, 2 vector ALU and 2 AGU per core [9] [10] Two load/store operations per CPU cycle for each memory channel
Some Intel processors have provisions to reduce the Turbo Boost frequency limit when such instructions are being executed. This reduction happens even if the CPU hasn't reached its thermal and power consumption limits. On Skylake and its derivatives, the throttling is divided into three levels: [66] [67] L0 (100%): The normal turbo boost limit.
The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
Core i5 and i7 support Turbo Boost 2.0. [ 81 ] Although it was initially supported on selected models, since August 2014 desktop variants no longer support TSX due to a bug that was discovered in its implementation; as a workaround, a microcode update disabled the TSX feature.
