AMD has a one year exclusivity on the external video cards

AMD talks up its new platform for laptops primarily thanks to the ability to connect on these machines an external video card via a NCV-Express train 8x connector. The card can then be used to connect an external screens or to accelerate integrated video.
Proof that they are pushing this platform is that they have signed a one year exclusive contract with JAE, the company which developed this connector.
Intel are a bit behind in the field of the video on portables compared to its competitors. All now propose solutions that use, in addition to the video integrated into the chipset, another more powerful chip that can be activated/deactivate when battery life is not crucial. They aim further with Larrabee, where it will be possible to choose the number of video cores that can be activated according to the required power.
