I am currently unrolling loops on the 3000 GPU inside the i5-2500 k in the assumption that the Execution Units handle the threads very much as the Stream processors in the Nvidia environment.
Can one see the Execution Units in the i5's GPU in this way ? Can each EU be viewed as an SIMD device ?
Is there a good description of what an EU actually is with regard to processing with the Compute Shader ? I have not been able to find one.
