Notebook PC makers and users desire the realism and performance of a discrete graphics processing unit (GPU), but they still demand maximum battery life. Now Sony, Fujitsu Siemens, and BenQ have announced the availability of notebooks that let users dynamically switch between a discrete NVIDIA® GeForce® GPU and Intel Centrino 2 integrated graphics without rebooting, giving users the choice of more visual computing performance or reducing power demands to extend battery life.
