AMD Guide explain changes in the current strategy, which involves the ability to integrate third-party products with different architectures in its own processors.
AMD Chapter Rory Reid, reported about the possibility of integrating third-party development in AMD processors, he cited the example of a partnership with some major tablets producer, smart phones, laptops, desktops, and smart TVs. Especially for such a partner, AMD can create a processor that combines x86-compatible architecture with an alternative.
Frankly, after these statements come to mind mainly two players: Apple and Samsung. As you know, the first use in smart phones and tablets are specially designed processor with ARM-architecture, which are produced at the Samsung facilities . Why Apple may need a processor that combines elements of both architectures are difficult to predict. Note that Intel and NVIDIA are going to integrate in their processors for smart phone modems, allowing to work in wireless networks. For AMD it would be the easiest and most obvious option of cooperation with third-party chips developer.
