Is NVIDIA’s Optimus tech the GPU future of the MacBook line?
Intel’s decision to marry their new mobile Core i5 and i7 CPUs with integrated graphics has reportedly not gone over well with Apple, who are rumored to be demanding custom-designed chips from Intel for an update to their MacBook and MacBook Pro line of notebooks.
But perhaps there’s another solution. Gizmodo noticed that NVIDIA, maker of the MacBook line’s ubiquitous GeForce 9400M GPU, is now teasing a new notebook technology called Optimus that is supposedly capable of achieving the performance of discrete graphics in a notebook while still delivering great battery life.
It’s probably just scalable performance, but if the Optimus tech is as good as NVIDIA is bragging, it would allow Apple to ditch the substandard switchable GPU configuration of current unibody MacBook Pros, which requires a reboot, to a discrete-only solution, like the earliest MacBook Pros and PowerBooks.
