The difference in the RADEON line of products lies in the memory configuration and architecture of each card. Our 64MB DDR card included 5.5ns Hyundai memory on a 128-bit bus, while the 32MB DDR version boasted 6ns Samsung RAM on the same bus. Finally the 32MB SDR RADEON uses 6ns Micron chips on the 128-bit bus.
Back in August we saw a couple of SDRAM boards floating around with DVI connectivity and 5ns (200MHz) Hyundai memory. Apparently, ATI decided to focus on the DDR products and not devote as many resources to the aging SDRAM architecture, making this a true OEM product.
We did find this box image on the French version of ATI's site:

Dotée de 32 Mo de SDRAM, c'est le meilleur rapport prix/performances de sa catégorie. (Well that's what it said)
Since the GPU on the SDRAM card is the same as on the more expensive DDR counterparts, all of the 3D acceleration features are alike. That's right, four-matrix skinning, keyframe interpolation, environmental bump mapping and all of the other 3D features are present and accounted for.
