[5] [6] This is surpassed by the CPU-Z overclocking record for the highest CPU clock rate at 8.79433 GHz with an AMD FX-8350 Piledriver-based chip bathed in LN2, achieved in November 2012. [7] [8] It is also surpassed by the slightly slower AMD FX-8370 overclocked to 8.72 GHz which tops off the HWBOT frequency rankings.
WPrime is popular in the overclocking community for testing the performance and stability of computer processors, as Super PI is single-threaded. Its popularity stemmed from being able to utilize 100% of a multi-core processor's computing time enabling its use as a multi-threaded benchmark application in competitions, [2] computing reviews, [3] and marketing campaigns.
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.

The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.
Case buttons including turbo button The LED display showing the CPU clock frequency, in MHz, of an Intel 80486 based computer. The turbo button is the small button below the segment display; the amber light above is a secondary indicator of the turbo button state.
For CPU-bound applications, clock doubling will theoretically improve the overall performance of the machine substantially, provided the fetching of data from memory does not prove a bottleneck. In more modern processors where the multiplier greatly exceeds two, the bandwidth and latency of specific memory ICs (or the bus or memory controller ...
Enhanced SpeedStep is a series of dynamic frequency scaling technologies (codenamed Geyserville [2] and including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel's microprocessors that allow the clock speed of the processor to be dynamically changed (to different P-states) by software.
In addition to the CPU drivers offered by AMD, several motherboard manufacturers have released software to give the end user more control over the Cool 'n' Quiet feature, as well as the other new features of AMD processors and chipsets. Using these applications, one can even control the CPU voltage explicitly. PhenomMsrTweaker (SourceForge link)
