1.8 Graphics Cards

• Graphics Card: Expansion card/component that decides how to use pixels to create a graphical image.
• GPU: Graphic Processing Unit - A CPU like circuit that specializes in processing information related to computer graphics and image processing
• Dedicated Graphics Card: Contains its own RAM, Contains its own Processing Unit (GPU), Contains its own Power Regulator, Contains its own Heatsinks, Contains integrated chips that are for graphics processing
• A GPU is a circuit that is designed for processing digital video image output, it’s integrated in motherboards or CPUs, and within dedicated graphics card
• The purpose of a GPU is to process display output anf to complete complex calculations to be shared with the system’s CPU and a GPU
• GPU Clock Speed: Determines how many calculations a GPU can calculate per second
• GPU Speeds: are calculated in Hz
• Faster the GPU, the better expected performance
• Video RAM (VRAM): An integrated RAM found in dedicated graphics card that allows simultaneous reading and writing of data
• VRAM: Mainly used for video-based memory, It is used to improve the performance of graphics cards, Allows the system to read data while sending data to a screen output simultaneous, the More VRAM the card has the better
