Video mem&videocards

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