ATI has announced that Apple's newly upgraded 15- and 17-inch PowerBook G4 notebooks, announced on April 19, feature the Mobility Radeon 9700 graphics card.

The company describes the graphics card as "the world's fastest mobile graphics processing unit."

The graphics processor uses Low-k process technology to reduce the strain on battery life and provide accelerated performance, according to ATI. According to EE Times, Low-k materials reduce capacitance and propagation delays within the interconnect layers of a device more effectively than mainstream silicon dioxide insulators, boosting overall chip performance and lowering power consumption.

The processor also "sets a new standard for processing power in a notebook, which enables users to perform a wide range of graphics functions, ranging from gaming, to digital video editing," claims ATI.

ATI vice president and general manager, mobile and integrated products Phil Eisler said: "With the introduction of the Mobility Radeon 9700, notebook performance no longer takes a backseat behind desktop products. By addressing the two key issues for notebook users, performance and power consumption, the Mobility Radeon 9700 demonstrates ATI’s commitment to user’s needs."

In addition, the eMac, upgraded on April 13, now features the Radeon 9200. ATI claims this enables "first class graphics at a low, entry-level price".
