The Cirrus Logic 5446 PCI is a graphics card (or graphics controller) that was commonly used in older systems, particularly in legacy HP machines like the HP VL6 series. It is typically a video controller used to drive displays in systems from the late 1990s and early 2000s. The PCI (Peripheral Component Interconnect) version means that it connects to the computer's motherboard through a PCI slot. This card uses the Cirrus Logic 5446 chipset, which was known for offering basic 2D and 3D graphics capabilities at the time.
