Dell CN-0C120D PCI Express Video Graphics Card

Dell CN-0C120D PCI Express Video Graphics Card is a Dell OEM ATI Radeon HD3470-based graphics card with 256 MB of memory designed for PCIe desktop systems. This discrete GPU plugs into a PCI Express x16 slot to deliver a modest upgrade over integrated graphics, enabling smoother visuals for older software, multimedia playback, and light gaming at standard or lower resolutions. Built around the ATI Radeon HD3470 core, the card provides basic 3D acceleration and improved image processing within its era of performance, making it a practical upgrade for legacy Dell or other PCIe-equipped desktops that need enhanced graphics without a major system overhaul. The CN-0C120D designation identifies this specific Dell OEM variant, and the 256 MB memory configuration aligns with typical HD3470 configurations used in budget or refurbished deployments. Compatibility depends on your motherboard’s PCIe slot availability and system BIOS constraints, so confirm PCIe support and GPU eligibility for your exact desktop model before installation.
