The benefit of electrically shutting off components in your notebook, including the GPU, is that it extends battery life. Compared to a standard notebook with a discrete GPU Optimus can extend battery life up to 2x*. The benefit of immediately turning it on again is, of course, that you get all the graphics and processing capabilities of the GPU at a moment’s notice. Few people ever get to see this demo because it requires a completely open notebook system – no chassis – just the motherboard, CPU, GPU, Hard drive, and monitor, so it is not exactly portable. This demo is really killer with engineering teams that design notebooks. They practically fall out of their chairs when they see it.
