Comparsion between Pixel Bender(in Flash) and Pixel Shaders(in Silverlight)

Question

Can someone explain the different between Pixel Bender in Flash and Pixel Shader(HLSL) in Silverlight in terms of programming flexibility and run-time performance?

Answer 1

I do not know about programmability, but as for run-time performance, pixelbender is great. Currently Silverlight 3 does not let you do this processing in the background, but with PixelBender, you can. This is good because the UI is not affected as much when using computationally intense filters.

This forum has some good pro's and con's for Silverlight 3: Pros and Cons. I know this topic is old, but I'm adding to it since it seemed a little incomplete.
