Today, February 9th 2010 marks the introduction of the final piece of the AMD DirectX 11 puzzle - the ATI Radeon HD 5570 is the final product of AMD's top-to-bottom DirectX 11 desktop graphics add-in boards.

Last week saw the entry-level ATI Radeon HD 5450 based on AMD's Cedar core, with the ATI Radeon HD 5670 introducing Redwood a couple of weeks prior to that. The HD 5570 slots in between the HD 5670 and the HD 5450 in terms of price, but not in terms of performance. The Redwood architecture is pruned to allow big features in small form factor (SFF) or Home Theater PC (HTPC).
