Study Notes

Video Cards

Video cards generate a computer's visual output, from basic text to complex 3D games. Graphic processing for games demands more than text-based programs.
Video cards consist of a GPU (Graphics Processing Unit) and video memory.
The GPU processes graphical information and sends it to a display. Heat management using heatsinks and fans is crucial.
Video memory stores graphical information requiring fast access.

Video Card Implementations

Integrated Graphics: Video card integrated with another component (e.g., motherboard or CPU).
Onboard Video Cards: Most common integrated solution, integrated with the motherboard. They are often sufficient and the least expensive option. They share system memory. Easily identified by video output ports on the I/O plate.
CPU-integrated graphics: Integrated with the CPU, also shares system memory.
Dedicated Video Cards: Installed into expansion slots. They contain a GPU, high-speed dedicated graphic memory (e.g., SGRAM, VRAM, GDDR3, 4, 5), and often large heatsinks and multiple fans for cooling. Typically used for gaming, 3D rendering. Much more expensive and powerful than integrated options.

Video Card Selection Considerations

Display Connectors: Match output connectors (VGA, DVI, S-Video, HDMI, DisplayPort, coaxial, or RCA) to your display device's connectors.
Display Capabilities: Match or exceed display device's resolution (number of pixels) and refresh rate. Consider video card memory matching or exceeding requirements of demanding graphics applications.
Memory Size: Select a card with at least the memory size recommended for the most demanding application. For example, if a game requires 2GB, select a card with at least 2GB of memory.
3D Graphics APIs: Many PC games use DirectX or OpenGL. Make sure the video card supports the latest API versions for the latest games.
Bus Types: Ensure motherboard and video card PCIe bus types (x16, x1) match for dedicated card installment.
Multi-GPU Support: Some cards have multi-GPU technology (e.g., NVIDIA SLI, AMD CrossFire) allowing multiple cards to work together. Multi-GPU configurations are expensive and benefit only demanding high-end computer systems.

Summary

Integrated graphics are sufficient for most needs.
For more processing power or memory, a dedicated video card is generally required.
Factors like memory size, connector compatibility, and bus type are important factors during the selection.
