The RV380 refers to the ATI Radeon X800 series graphics card, which is part of the Radeon X800 family produced by ATI Technologies, a company acquired by AMD. The RV380 specifically corresponds to a certain variant of the Radeon X800 graphics cards, often used in older desktops and laptops. These graphics cards support hardware acceleration for graphics-intensive tasks such as 3D rendering, gaming, and video playback.

The RV380 Windows driver is the software that allows Windows operating systems (like Windows 10 or Windows 11) to communicate with and use the graphics card. It provides functionality for your graphics hardware, including rendering graphics, managing display output, controlling graphics settings, and enabling hardware-accelerated features.
