AMD's Radeon HD 5450 is the first and only low-end DirectX 11 capable graphics card. It is designed in a way to make it the premier choice for silent media PC systems that still pack enough punch to decode full HD content. Another important field of engineering for such a product is energy efficiency, not only because it is more environmentally friendly and reduces operating costs, but reduced power draw also means less heat, which allows less complex cooling solutions resulting in less fan noise.
