Radeon

Radeon /ˈreɪdiːɒn/ is a brand of graphics processing units and random access memory produced by Advanced Micro Devices. The brand was launched in 2000 by ATI Technologies, which was acquired by AMD in 2006. Radeon is the successor to the Rage line. There are four different groups, which can be differentiated by the DirectX generation they support. More specific distinctions can also be followed, such as the HyperZ version, the number of pixel pipelines, and of course, the memory and processor clock speeds.
