AMD Turbo Core a.k.a. AMD Core Performance Boost (CPB) is a dynamic frequency scaling technology implemented by AMD that allows the processor to dynamically adjust and control the processor operating frequency in certain versions of its processors which allows for increased performance when needed while maintaining lower power and thermal parameters during normal operation.

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.
Several computer systems introduced in the 1960s, such as the IBM System/360, DEC PDP-6/PDP-10, the GE-600/Honeywell 6000 series, and the Burroughs B5000 series and B6500 series, support two CPU modes; a mode that grants full privileges to code running in that mode, and a mode that prevents direct access to input/output devices and some other hardware facilities to code running in that mode.
C-states are disabled, therefore the CPU will constantly run at its highest frequency and voltage; Turbo-boost is disabled; Integrated graphics are disabled; AVX2 instruction performance is poor, approximately 4-5 times slower due to the upper 128-bit half of the execution units and data buses not being taken out of their power saving states
As the name implies, this is a step up for people for whom even the High Performance mode isn't enough -- it throws power management out the window to eliminate "micro-latencies" and boost raw speed.
[4] [5] [6] The 10ESF has a 10%-15% boost in performance over the 10SF used in the mobile Tiger Lake processors. Intel officially announced 12th Gen Intel Core CPUs on October 27, 2021, [ 7 ] mobile CPUs and non-K series desktop CPUs on January 4, 2022, [ 8 ] Alder Lake-P and -U series on February 23, 2022, [ 9 ] and Alder Lake-HX series on May ...
Haswell-EP models with ten and more cores support cluster on die (COD) operation mode, [75] allowing CPU's multiple columns of cores and last level cache (LLC) slices to be logically divided into what is presented as two non-uniform memory access (NUMA) CPUs to the operating system. By keeping data and instructions local to the "partition" of ...
