PC-WELT:

It’s obvious as well that the next ATI generation (R520) will support the shader model 3.0. What are the benefits of the shader model 3.0?

Raja Koduri:

A well implemented and efficient shader model 3.0 offers some performance optimization opportunities for the ISV (Independent Software Vendor). The most significant feature for shader model 3.0 is branching – which is the ability to skip executing a bunch of instructions conditionally. Now, this is only going to benefit performance if the cost of branching is lower than the amount of work you are skipping.
