Future MacBooks to Improve Dual Graphics Chip Handling?

Apple plans to improve the handling of dual graphics chips in future MacBook Pro models, according to an AppleInsider report.

According to sources, in its labs Apple has up and running several next-generation MacBook Pros which can switch been the integrated and discrete graphics processors automatically.

Currently the existing MacBook Pros require users to manually toggle between an integrated Nvidia GeForce 9400M graphics core and the more powerful 9600M GT discrete processor using the Energy Saver system preference pane. Once you have made the change you need to log in and out for it to take effect.


AppleInsider suggests that a new Nvidia technology called Optimus could make its way to the MacBook Pro. Optimus was designed to work alongside Nehalem notebook designs that have both an integrated Intel graphics processor and a discrete Nvidia graphics chip. It chooses the best of the two graphics processors for running a given application and automatically routes the workload to either the discrete Nvidia chip or Intel integrated graphics core. This provides the best performance while also providing optimal battery life.

"Just as a Hybrid car chooses between the gas-powered and electric car engine on-the-fly and uses the most appropriate engine, Nvidia Optimus technology does the same thing for graphics processors," Nvidia explains. "Optimus Technology instantly directs the workload through the most efficient processor for the job, extending battery life by up to 2 times compared to similarly configured systems equipped with discrete graphics processors."
