Yeah, that's not how GPUs work. They have a number of shader 
units that execute on outputs in parallel. It used to be an 
explicit split between vertex and pixel pipelines in the early 
days, where it was very easy to underutilise the vertex pipeline. 
But shader units have been unified for a long time. Queue up a 
bunch of outputs and the driver and hardware will schedule it 
properly.
