  2. GPU switching - Wikipedia

    en.wikipedia.org/wiki/GPU_switching

    The discrete graphics card is usually installed onto the graphics card slot such as PCI-Express and the integrated graphics is integrated onto the CPU itself or occasionally onto the Northbridge. [ citation needed ] The Northbridge is the most responsible for switching between GPUs.

  3. Shared graphics memory - Wikipedia

    en.wikipedia.org/wiki/Shared_graphics_memory

    The disadvantage of this design is lower performance because system RAM usually runs slower than dedicated graphics RAM, and there is more contention as the memory bus has to be shared with the rest of the system. It may also cause performance issues with the rest of the system if it is not designed with the fact in mind that some RAM will be ...

  4. Graphics card - Wikipedia

    en.wikipedia.org/wiki/Graphics_card

    A modern consumer graphics card: A Radeon RX 6900 XT from AMD. A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor.

  5. Graphics processing unit - Wikipedia

    en.wikipedia.org/wiki/Graphics_processing_unit

    Components of a GPU. A graphics processing unit (GPU) is a specialized electronic circuit initially designed for digital image processing and to accelerate computer graphics, being present either as a discrete video card or embedded on motherboards, mobile phones, personal computers, workstations, and game consoles.

  6. Southbridge (computing) - Wikipedia

    en.wikipedia.org/wiki/Southbridge_(computing)

    The other component of the chipset is the northbridge, which generally handles high speed onboard communications. A southbridge chipset handles functions such as USB, audio, the system firmware, the lower speed PCI/PCIe buses, the IOAPIC interrupt controller, the SATA storage, the historical PATA storage, the NVMe storage, and low speed buses ...

  7. Graphics hardware - Wikipedia

    en.wikipedia.org/wiki/Graphics_hardware

    The price of graphics hardware varies with its power and speed. Most high-end gaming hardware are dedicated graphics cards that cost from $200 up to the price of a new computer. In the graphics cards department, using integrated chips is much cheaper than buying a dedicated card, however the performance conforms to the price.

  8. Nvidia Optimus - Wikipedia

    en.wikipedia.org/wiki/Nvidia_Optimus

    Nvidia Optimus is a computer GPU switching technology created by Nvidia which, depending on the resource load generated by client software applications, will seamlessly switch between two graphics adapters within a computer system in order to provide either maximum performance or minimum power draw from the system's graphics rendering hardware.

  9. Intel GMA - Wikipedia

    en.wikipedia.org/wiki/Intel_GMA

    The performance and functionality of GMA processors are limited, attaining the performance of only low-cost discrete GPUs at best and very old DirectX 6 GPUs (Such as the RIVA TNT2) at the worst. Thus, they're sometimes even dubbed "Graphics Media Decelerators" though the actual performance depended on the CPU as well as RAM amount and speed.
