The ATI Radeon HD 5850 is a high-end graphics card released in September 2009. Supporting up to three displays, the 1GB GDDR5 GPU incorporates a long list of advanced technologies, including ATI Stream, enabling large-scale parallel processing, and ATI CrossFireX, which provides scalability with multi-GPU support. The HD 5850 is also one of the first cards to support DirectX 11. It is a minor step down from the top-of-the-line model, the HD 5870, which offers even higher clock frequencies and memory bandwidth.
