ATi has some cool innovations on the mobile front that might pose some challenges to NVIDIA. We heard that ATi is going to implement Power Express Technology into their future Catalyst drivers or thru a separate software that enables hot switching between IGP and discrete graphics. This will allow the notebooks featuring ATi discrete graphics onboard to switch over to IGP instantly when battery mode is on or when not running 3D applications to conserve precious battery power. Right now, Intel Napa platform and NVIDIA C51 chipsets have the ability to shutdown PCI Express lanes to conserve power so ATi’s Power Express Technology is really a step in front. By shutting down the discrete graphics on a notebook featuring mobility X700, it will reduce the power consumption by a third.
