  1. Video Cards By Ben Marsh

  2. Some History For Video Cards • The first video card was the Monochrome Display Adapter (MDA). Introduced in 1981 by IBM. It had 4 kilobytes of video memory. It also had a printer adapter.

  3. History Of Video Cards (Continued) • In 1995 the first consumer 2D/3D cards were released, developed by Matrox, Creative, S3, ATI and others.

  4. History Of Video Cards (Continued Some More) • 3dfx released its Voodoo Graphics chip in 1996. Powerful compared to other consumer graphics cards, introducing 3D effects into the market.

  5. History Of Video Cards (Yet Again Continued) • The Voodoo2 was released in 1998. The Voodoo2 required a separate onboard 2D Video card for non 3D Gaming. The image quality passed the Voodoo by far. It had higher resolutions (1024x768). It had multitexturing support, resulting in four times better performance if supported.

  6. History Of Video Cards (Look Its Still Going) • In 1995 Nvidia NV5 had double the onboard memory of the NV4 Video card, which was 16MB, (The NV5 Had 32MB) It Also ran 70% faster than the NV4 Card.

  7. History Of Video Cards (Hey Look Even More) • 3dfx Was bought out by NVIDIA in December of 2000. When NVIDIA did so the video card 3dfx was currently working on, the Rampage, was put to a halt.

  8. History Of Video Cards (It Doesn’t Stop Here) • In 2002 Matrox produced the Parhelia. It had 256-Bit memory, it came clocked at 220MHz and had support for three monitors. It also was supposed to support Direct X9. It did not have support for Direct X9, and its retail price was $400.00. Double the price for the same Specs other competitors were producing.

  9. Video Cards Today • Video Cards compared from 1981 to Now, in 2009 have changed a lot. One video card now can support 4 monitors and are literally hundreds of thousands times faster and can handle so much more at once. If you compared the Monochrome Display Adapter to a Geforce GTX 275 there not even in the same ballpark. The MDA had 4kb of video memory while the Geforce GTX 275 has 1.7Gb (1792Mb) of video memory.

  10. Video Card Components Terminology • Motherboard Connections : Bring in data from the hard drive and electricity from the power supply. • Memory Chips : Hold the data during processing. • Graphics Processor Chips : Turn digital data into pixel information. • Monitor Connections: Send pixels to the monitor.

  11. Video Card Connections • AGP : Designed for use with 3d Graphics. AGP used a point to point channel for direct access to the main memory. It has a bandwidth of 266 Mbps to 1.07 Gbps. To use this video card your motherboard needs to have a slot to support it. Most modern computers do support this type of card. • PCI : The oldest of the three types of video cards. Uses a shared bus to allow communication among different devices on the bus. It has a bandwidth of up to 133 Mbps to 512 Mbps. They can still offer decent performance if above 128Mbps. • PCI-E : PCI Express doubles the data transfer rates of a standard PCI card. PCI-E is on a two way serial connection, avoiding the slowdown of sharing a bus. It also uses other devices, like a network card to get greater output. PCI-E is compatible with some existing PCI systems. It is the replacement for AGP.

  12. What They Look Like PCI PCI-E AGP

  13. Video Card Monitor Connection Terminology • Video Graphics Adapter : VGA connects to analog monitors. • Digital Visual Interface : DVI connects to digital display devices, LCD monitors and digital projectors. • S-Video : S-Video used to connect a PC video card to a television, only capable of 480i or 576i resolution. • High Definition Multimedia Interface : HDMI connects a computer to your HDTV set.

  14. How The Video Card Works • The Video Card is a circuit. It is responsible for processing video data from the CPU so that the monitor can understand it and create a picture on the screen. The Video Chipset, the Video Ram and the Digital Analog Converter are all things that are used to do this.

  15. How The Video Card Makes A Picture • First, the Video data is transferred from the CPU to the Video cards chipset it then processes the data. The data is then transferred from the Video chipset to the Video Memory. The video memory stores the image. The data is then transferred from the video memory to the digital analog converter. The digital analog converter converts the image from digital data to analog data. The analog data is then transferred to the monitor through whatever cable it is using. For example, VGA, DVI, S-Video, or HDMI cables.

  16. What's a GPU? • A graphics card processor is called a Graphics processing Unit (GPU). It is designed for performing mathematical and geometric calculations that are needed for graphics rendering. Basically it’s the graphics cards CPU. It Processes the data

  17. Who Makes GPUs • ATI and NVIDIA produce a large amount of the GPUs on the market. To create better image quality there processors use: • Full scene anti aliasing (FSAA) : Smoothes the edges of 3-D objects. • Anisotropic filtering (AF) : Makes images look more defined.

  18. Who Makes Video Cards? • Asus, BFG, Chaintech, ECS, eVGA, Foxconn, Gigabytem, MSI, PNY, And XFX,
