  2. Single-core - Wikipedia

    en.wikipedia.org/wiki/Single-core

    A computer using a single core CPU is generally slower than a multi-core system. Single core processors used to be widespread in desktop computers, but as applications demanded more processing power, the slower speed of single core systems became a detriment to performance. Windows supported single-core processors up until the release of ...

  3. Multithreading (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Multithreading_(computer...

    A process with two threads of execution, running on a single processor . In computer architecture, multithreading is the ability of a central processing unit (CPU) (or a single core in a multi-core processor) to provide multiple threads of execution.

  4. CPU-bound - Wikipedia

    en.wikipedia.org/wiki/CPU-bound

    Establishing that a computer is frequently CPU-bound implies that upgrading the CPU or optimizing code will improve the overall computer performance. With the advent of multiple buses, parallel processing, multiprogramming , preemptive scheduling, advanced graphics cards , advanced sound cards and generally, more decentralized loads, it became ...

  5. 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:

    1.344×10 12 GeForce GTX 480 in 2010 from Nvidia at its peak performance; 2.15×10 12: iPhone 15 Pro September 2023 A17 Pro processor; 4.64×10 12: Radeon HD 5970 in 2009 from AMD (under ATI branding) at its peak performance; 5.152×10 12: S2050/S2070 1U GPU Computing System from Nvidia; 11.3×10 12: GeForce GTX 1080 Ti in 2017; 13.7×10 12 ...

  7. Simultaneous multithreading - Wikipedia

    en.wikipedia.org/wiki/Simultaneous_multithreading

    The term multithreading is ambiguous, because not only can multiple threads be executed simultaneously on one CPU core, but also multiple tasks (with different page tables, different task state segments, different protection rings, different I/O permissions, etc.). Although running on the same core, they are completely separated from each other.

  8. SPECint - Wikipedia

    en.wikipedia.org/wiki/SPECint

    This range of capabilities, specifically in this case the number of CPUs, means that the SPEC INT benchmark is usually run on only a single CPU, even if the system has many CPUs. If a single CPU has multiple cores , only a single core is used; hyper-threading is also typically disabled,

  9. LINPACK benchmarks - Wikipedia

    en.wikipedia.org/wiki/LINPACK_benchmarks

    The aim is to approximate how fast a computer will perform when solving real problems. It is a simplification, since no single computational task can reflect the overall performance of a computer system. Nevertheless, the LINPACK benchmark performance can provide a good correction over the peak performance provided by the manufacturer.
