As odd it may seem, the story holds ground and is one of the useful steps for the Centrino 2 platform of notebooks. Fuad Abazovic of Fudzilla claims that AMD is working hard with Intel to develop switchable graphics in future Centrino laptops. AMD is doing this in the notebooks with Puma and wants to have similar technology in notebooks with Intel chips and ATI/AMD graphic cards.
The thing about switchable graphics is that when your laptop is connected to the power unit or had good battery, it will use the graphics card. When the battery is low, it will switch to the onboard graphics. This will save power and make your battery life increase a little. Its generally close to 5-10% improvement, we heard the last time. But for the dying moments of laptop battery, I have experienced that you always remember the important work.
If you look at the image above, you'll see that the plus sign is red, just like red-cross... That's because it's one of the good things being done on the battlefield between Intel and AMD. This news makes you think how bitter rivals AMD and Intel are working together?? But actually its ATI which is working with Intel and I'm sure AMD has told its engineers not to look, talk, have lunch or discuss anything with Intel engineers. They just make faces when they meet and exchange some white documents with each other... Infact, news is that some even show the "middle-finger" to each other :))
