I don't understand the need for reserved CUs. GPGPU is perfectly doable on a classic GPU, without the need to have dedicated units for that.
In the end even the orbis GPU might be used for computational stuff, and so is the Durango one.
I think what will really matters is the number of CUs. Having a part of them arbitrary assigned to a task may come off as a constraint more than anything else.
They are probably not reserved like that. Usually all the components of a gpu scales with the compute units. This could very well mean that scaling everything to have a 18CU gpu would be too expansive, and so they decided to scale all the other parts of the gpu to 14CUs and provided extra float point performance that wouldn't make much difference for graphics, but is useful for other tasks.
