AMD continues their procession of new ATI Radeons today, with a couple of new entry-level offerings targeted at users who would like to upgrade from underpowered IGPs. Like the Radeon HD 4670 that came before it, the new Radeon HD 4550 and HD 4350 being rolled out today are based on the same GPU architecture first introduced with the popular Radeon HD 4800 series. The Radeon HD 4550 and HD 4350 both offer support for DirectX 10.1, DisplayPort, AVIVO with the UVD 2 engine, and CrossFire, although they do not have CrossFire bridge connectors like AMD's higher-end offerings. As such, these new entry-level cards sport virtually all of the same features as their more expensive, and more powerful, counterparts--they just don't perform on the same level.
