  2. Clock rate - Wikipedia

    en.wikipedia.org/wiki/Clock_rate

    [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.

  3. Spread spectrum - Wikipedia

    en.wikipedia.org/wiki/Spread_spectrum

    Moreover, for a given noise power spectral density (PSD), spread-spectrum systems require the same amount of energy per bit before spreading as narrowband systems and therefore the same amount of power if the bitrate before spreading is the same, but since the signal power is spread over a large bandwidth, the signal PSD is much lower — often ...

  4. Overclocking - Wikipedia

    en.wikipedia.org/wiki/Overclocking

    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.

  5. Dynamic frequency scaling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_scaling

    ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...

  6. Process gain - Wikipedia

    en.wikipedia.org/wiki/Process_gain

    Resistance of spread-spectrum system against narrowband interference. In a spread-spectrum system, the process gain (or "processing gain") is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. Research suggests that it is one of the important factors in making decisions over the performance of system in jamming ...

  7. Iron law of processor performance - Wikipedia

    en.wikipedia.org/wiki/Iron_law_of_processor...

    Classic Complex Instruction Set Computer (CISC) ISAs optimized by providing a larger set of more complex CPU instructions. Generally speaking, however, complex instructions inflate the number of clock cycles per instruction C l o c k C y c l e s I n s t r u c t i o n {\displaystyle \mathrm {\tfrac {ClockCycles}{Instruction}} } because they must ...

  8. Frequency scaling - Wikipedia

    en.wikipedia.org/wiki/Frequency_scaling

    In computer architecture, frequency scaling (also known as frequency ramping) is the technique of increasing a processor's frequency so as to enhance the performance of the system containing the processor in question. Frequency ramping was the dominant force in commodity processor performance increases from the mid-1980s until roughly the end ...

  9. Zero-overhead looping - Wikipedia

    en.wikipedia.org/wiki/Zero-overhead_looping

    In computer architecture, Zero-overhead looping is a hardware feature found in some processors that enables loop s to execute without the performance cost of traditional loop control instructions. Instead of software managing loop iterations, the processor's hardware handles repetition automatically, saving clock cycles and improving efficiency.
