A discrete video card is a dedicated circuit board designed to process graphical data independently of a computer's central processor. Unlike integrated graphics, which are built into the CPU or motherboard, a discrete video card is a separate component that typically includes the following parts:

Graphics Processing Unit (GPU): The primary processing chip containing multiple cores that perform the complex calculations required to render 3D models, textures, and lighting.1
Video Memory (VRAM): Dedicated memory chips that store graphical data, such as image buffers and textures, allowing the GPU to access information quickly.1
Motherboard Interface: A set of connector pins, typically using the Peripheral Component Interconnect Express (PCIe) standard, that connects the card to the computer.1
Power and Display Connectors: Dedicated power inputs and output ports (such as HDMI) to supply electricity and transmit signals to a display.1
Voltage Regulator Module (VRM): Components that manage and stabilize the power supply to the card.1
Cooling System: A heat sink, fans, or liquid-cooling system to dissipate the heat generated during high-performance tasks.1
Firmware: Chips hosting the Basic Input/Output System (BIOS) to manage the card's operation.1
