I am new to GPGPU and have noticed that AMD/ATI offers two diferent languages for programming their cards: Brook and CAL. I look at the SDK and CAL seems a lowest level language than Brook. I have two questions:

Are there significant differences between CAL and Brook at the time to take control over the execution? i.e. Can CAL do things on the hardware that can not be done in Brook?

Gives CAL more performance than Brook?

Thank you
