A Processor View of "Post PC"

At the processor level, here is one way of looking at the "post PC" trend. Because of a fall in sales of PCs, AMD has fallen from the number-two spot for processors to the fourth position, in terms of market share. 

Qualcomm and Samsung moved up, both on the strength of sales of mobile processors. 

AMD's market share dropped 21 percent, year over year, between 2011 and 2012, while Intel dropped one percent. Samsung, which supplies processors for Apple, among others, grew share 78 percent, while Qualcomm grew share 28 percent.
