Video Card
The video card is measured in 5 things:
GPU clock speed: Is the speed in which the GPU executes instructions. The higher the GPU clock rate, the faster the GPU. It is is measured megahertz (MHz) or gigahertz (GHz).
RAMDAC speed (MHz): Its job is to convert digitally encoded images in analog signals that can be displayed on the monitor. TH more RAMDAC speed the faster and smoother images will appear on the monitor. It is measured in MHz.
