What is a discrete graphics card?

A discrete graphics card, also known as a dedicated graphics card or GPU (Graphics Processing Unit), is a separate component installed in a computer system to handle graphics processing tasks. Unlike integrated graphics, which are built into the computer's motherboard or processor, a discrete graphics card has its own dedicated memory and processing power. This allows for better performance and visual quality in graphics-intensive tasks such as gaming, video editing, and 3D rendering.

Discrete graphics cards come in various forms and configurations, ranging from entry-level cards for casual users to high-end cards for hardcore gamers and professionals. They are typically connected to the computer's motherboard via a PCI Express slot and require their own power supply. Some high-end graphics cards may also feature additional cooling systems such as fans or liquid cooling to prevent overheating.

When choosing a discrete graphics card, factors to consider include the GPU model and architecture, amount of memory (VRAM), power consumption, and compatibility with the rest of the computer system. Upgrading to a discrete graphics card can significantly improve the performance and visual quality of a computer, especially for tasks that require intensive graphics processing.
