  2. Clock rate - Wikipedia

    en.wikipedia.org/wiki/Clock_rate

    Further, a "cumulative clock rate" measure is sometimes assumed by taking the total cores and multiplying by the total clock rate (e.g. a dual-core 2.8 GHz processor running at a cumulative 5.6 GHz). There are many other factors to consider when comparing the performance of CPUs, like the width of the CPU's data bus , the latency of the memory ...

  3. CPU multiplier - Wikipedia

    en.wikipedia.org/wiki/CPU_multiplier

    For example, a system with an external clock of 100 MHz and a 36x clock multiplier will have an internal CPU clock of 3.6 GHz. The external address and data buses of the CPU (often collectively termed front side bus (FSB) in PC contexts) also use the external clock as a fundamental timing base; however, they could also employ a (small) multiple ...

  4. Megahertz myth - Wikipedia

    en.wikipedia.org/wiki/Megahertz_myth

    As of 2018, many Intel microprocessors are able to exceed a base clock speed of 4 GHz (Intel Core i7-7700K and i3-7350K have a base clock speed of 4.20 GHz, for example). In 2011, AMD was first able to break the 4 GHz barrier for x86 microprocessors with the debut of the initial Bulldozer based AMD FX CPUs. In June 2013, AMD released the FX ...

  5. Multi-core processor - Wikipedia

    en.wikipedia.org/wiki/Multi-core_processor

    A multi-core processor (MCP) is a microprocessor on a single integrated circuit (IC) with two or more separate central processing units (CPUs), called cores to emphasize their multiplicity (for example, dual-core or quad-core). Each core reads and executes program instructions, [1] specifically ordinary CPU instructions (such as add, move data ...

  6. Computer performance - Wikipedia

    en.wikipedia.org/wiki/Computer_performance

    In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:

  7. 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.

  8. Front-side bus - Wikipedia

    en.wikipedia.org/wiki/Front-side_bus

    The frequency at which a processor (CPU) operates is determined by applying a clock multiplier to the front-side bus (FSB) speed in some cases. For example, a processor running at 3200 MHz might be using a 400 MHz FSB. This means there is an internal clock multiplier setting (also called bus/core ratio) of 8. That is, the CPU is set to run at 8 ...
