  2. Superposition Benchmark - Wikipedia

    en.wikipedia.org/wiki/Superposition_Benchmark

    The scene is GPU-intensive because of SSRTGI (Screen-Space Ray-Traced Global Illumination), proprietary dynamic lighting technology by Unigine. Superposition and other benchmarks by Unigine are often used by hardware reviewers to measure graphics performance ( PCMag , [ 1 ] [ 2 ] [ 3 ] Digital Trends , [ 4 ] [ 5 ] [ 6 ] Lifewire [ 7 ] [ 8 ] [ 9 ...

  3. Performance per watt - Wikipedia

    en.wikipedia.org/wiki/Performance_per_watt

    Graphics processing units (GPU) have continued to increase in energy usage, while CPUs designers have recently [when?] focused on improving performance per watt. High performance GPUs may draw large amount of power, therefore intelligent techniques are required to manage GPU power consumption.

  4. General-purpose computing on graphics processing units

    en.wikipedia.org/wiki/General-purpose_computing...

    This representation does have certain limitations. Given sufficient graphics processing power even graphics programmers would like to use better formats, such as floating point data formats, to obtain effects such as high-dynamic-range imaging. Many GPGPU applications require floating point accuracy, which came with video cards conforming to ...

  5. Performance tuning - Wikipedia

    en.wikipedia.org/wiki/Performance_tuning

    See the main article at Performance engineering. Performance engineering is the discipline encompassing roles, skills, activities, practices, tools, and deliverables used to meet the non-functional requirements of a designed system, such as increase business revenue, reduction of system failure, delayed projects, and avoidance of unnecessary usage of resources or work.

  6. Huang's law - Wikipedia

    en.wikipedia.org/wiki/Huang's_law

    In 2006, Nvidia's GPU had a 4x performance advantage over other CPUs. In 2018 the Nvidia GPU was 20 times faster than a comparable CPU node: the GPUs were 1.7x faster each year. Moore's law would predict a doubling every two years, however Nvidia's GPU performance was more than tripled every two years, fulfilling Huang's law. [5]

  7. Hardware acceleration - Wikipedia

    en.wikipedia.org/wiki/Hardware_acceleration

    Hardware accelerators improve the execution of a specific algorithm by allowing greater concurrency, having specific datapaths for their temporary variables, and reducing the overhead of instruction control in the fetch-decode-execute cycle. Modern processors are multi-core and often feature parallel "single-instruction; multiple data" units ...
