Graphics Cards

Graphic Processing Units (GPU) connect to the motherboard in different ways, PCI, AGP or more commonly these days PCIe. Motherboards can supply the power though on enthusiast GPU's they generally require a direct connection to the PSU. A GPU processes mathematical calculations which produces an output to be displayed on a monitor. A GPU takes binary data from the CPU and creates pixels which makes up the image displayed on the monitor.

There are 3 different types of GPU

  • Integrated - Most motherboards have integrated graphics capabilities and function without a separate GPU
  • Dedicated - These graphics cards connect via an AGP, PCI or PCIe slot, usually requiring a direct connection to the power supply
  • Hybrid - Normally found in notebooks.

GPU Specifications

GPU Architecture - The platform or technology a GPU is built on.

Core Clock Speed - The frequency at which the GPU is running, measured in MHz.

Onboard Memory - Available memory measured in Mb or Gb

Memory Clock Rate - Measured in MHz

Memory Bandwidth - Determines the memory bandwidth, Measured in Gbs

Transistor Count - The number of transistors in the GPU

RAMDAC - Digital-to-Analog converter measured in MHz
