&gt;Apple has had GPU switching for quite a while (my 2010 MacBook Pro has it, and I don&#x27;t think it was the first). So clearly MS didn&#x27;t invent that.<p>Adding to this: Nvidia has also been advertising GPU switching for quite a while now, under the Optimus brand. I don&#x27;t think it&#x27;s a coincidence that MS went with Nvidia over AMD for the SB.
