The main thing to note is that when selecting the GPU as the rendering device, Arnold will disable the sliders for every sampling type aside from Camera (AA).

While there are some options disabled with Arnold GPU for the time-being, the overall UI thankfully remains the same (at least in Maya and 3ds Max). In some renderers, changing between the CPU and GPU might reflect a change to the UI, since options may differ between them.
