Loaded with the latest features, ATI RadeonTM HD 4600 Series graphics cards deliver a level of gaming performance previously only found in high-end graphics cards. Redefine the way you play HD games and enjoy unprecedented levels of graphics realism powered by 320 stream processing units, up to 512MB of memory and support for Microsoft DirectX 10.1 games. Upgrade your graphics card and watch Blu-ray movies and play HD content with incredible visual fidelity1. These graphics cards do it all with break-through energy efficiency, eliminating the need for an external power connection and making them easy to install. With its 92mm cooling fan, this soon to be part of the Professional Cool Solution (PCS) product line, increases air flow at a lower fan speed that easily dissipates heat from an optimized heat sink which fully covers the PWM and memory. The special fan design avoids direct contact with high temperatures emanating from the heat sink, extending the life cycle of the cooling fan. Keeping fan noise at a minimum, the fan speed automatically adjusts while it’s under idle, in 2D or 3D mode—helping to deliver the perfect heat dissipation, allowing a better user experience.
