Radeon HD 4830 is an underclocked HD4850

exPreview has discovered that the Radeon HD 4830 supports 800 stream processors, rather than the advertised 640.  This makes it similar to the HD 4850, it simply runs at a lower clock speed.  However, it’s easily overclocked to run at the same speed, and retails for $89.99, rather than $114.
