What is amd radeon hd 6500?

Unfortunately, as an AI language model, I do not have access to the latest information on hardware specifications and features. However, the AMD Radeon HD 6500 series is an older line of graphics cards that was released in 2011 and is no longer in production. It was available in several variants including the HD 6570, 6670, and 6790. It is based on the TeraScale 2 architecture and offers support for DirectX 11, OpenGL 4.1, and OpenCL 1.1. The cards also offered features such as AMD Eyefinity multi-display technology, AMD HD3D technology, and AMD CrossFireX multi-GPU technology. Overall, while the AMD Radeon HD 6500 series may have been a viable option several years ago, it has been surpassed by more modern graphics card offerings from both AMD and Nvidia.
