  • 1. Video Cards, Video Memory
    By Cam Cummings & Nigel Gray
  • 2. Video Memory
    Video Memory is used to store image data for a computer display in order to speed the processing and display of video and graphics images.
  • 3. Different Types of Video Memory
    RAM
    VRAM
    SD Card
  • 4. RAM
    RAM (Random-Access Memory)
    RAM is computer data storage that can be accessed in any random order
  • 5. SD Card
    Secure Digital Card (SD)
    A non-volatile memory card
    Digital Camera
  • 6. VRAM
    Video Random-Access Memory (VRAM)
    A dual ported variant of Dynamic RAM (DRAM)
  • 7. Why is Video Memory significant?
    1) Processes images and displays it on the monitor
    2) Takes some of the workload for the CPU
    3) Allows your computer to run smoothly while multi-tasking
  • 8. Additional Information
    The more the better
    Every PC has at least 250MB (not very much)
    You can add/remove
    Video Memory is also provided
    on a Video Graphics Card
  • 9. Video Memory Summary
    Key points:
    1) Intermediate storage area between the microprocessor and the display
    2) There are different/variations of video memory
    3) Helps speed up a computer’s performance
    4) Every computer has some
    5) The more the better
  • 10. Video Cards
    A video card (graphics card) combines video processing and storage onto an expansion card, or integrated onto the motherboard to manage video images for display.
  • 11. What they are all about
  • 12. Difference between integrated graphics
    Some graphics can be Integrated, which means it’s wired onto the circuit (mother) board.
    Video cards are separated devices that you can buy and install
    You can update integrated graphics
    Video Cards are usually more powerful
    VS
  • 13. What’s useful about having a video card?
  • 14. Why they matter
    Provide capabilities for today’s graphics-intensive software like on Windows 7 or Mac OS X.
  • 15. Different Kinds of Video Cards
    PCI (Peripheral Component Interconnect)
    PCI –E (Peripheral Component Interconnect Express)
    AGP (Accelerated Graphics Port)
    All are different kinds of video ports for a computer’s motherboard. The difference between these are the pin holes.
    AGP Supports PCI/PCI-E Supports
  • 16. Is one kind better than the other?
    No
    It’s a matter of preference.
    AGP supported graphics cards usually have better support drivers but lack in processing power
    PCI/PCI-E has better processing power and lack in support drivers
  • 17. Essential Information
    Most have a GPU
    Takes load off:
    -CPU
    -Video Memory
    -Video BIOS
    Video cards contain their own RAM usually in 128MB or 250MB
  • 18. Video Card Summary
    Video cards are an add-on to a computer’s motherboard that processes images and display them. It helps process video memory for the CPU, RAM, and video BIOS so it won’t bog down the computer.
