GPUs are already pretty generic. The main diff is that a GPU will execute N threads in lockstep, where N = 32 or 64, like a very wide and always-on SIMD. The dedicated render pipeline still exists, and is still needed for things like Z buffering and interpolation, but you'd be surprised how much of what used to be fixed hardware is being emulated by the driver.
