Curie is the codename for a GPU microarchitecture developed by Nvidia, and released in 2004, as the successor to the Rankine microarchitecture. It was named with reference to the Polish physicist Marie Salomea Skà ÂodowskaâÂÂCurie and used with the GeForce 6 and 7 series. Curie was followed by Tesla.
The lack of unified shaders makes DirectX 9.0c the last supported version of DirectX for GPUs based on this microarchitecture.
