AMD's Lisa Su said in an interview at Citi Global Technology Conference that AMD isn't competing in the mobile phone space because it's already too crowded and not a good allocation of their resources or words to that effect. I've read the entire transcript. I'm long AMD stock and options and would love to believe that but it just isn't true.
The biggest reason I ask is for the last couple of years all I've read about is Apple acquiring the necessary pieces to design their own SoC's for their devices. If AMD is still involved this is excellent!
