Hardware branded as "DirectX 8" does Shader model v1.1. Hardware branded as "DirectX 9" does Shader model v2.0. I think there is also a Shader model v3.0, but I'm not sure what/if any hardware does that yet. Probably a Vista/DirectX 10 thing. Anyway, to answer your question. I believe nVidia & ATI have some optimized "features" that can be exploited, but the language itself is probably the same.
