There has been a lot of talk over the past few months about the move to 64-bit processors mobile processors. Obviously, the talk began with Apple's surprise announcement that the A7 system-on-a-chip (SoC) that would be found in the iPhone 5s was a 64-bit processor, making it the first 64-bit processor in a smartphone.
But, as always happens when Apple does something like this, there is a debate about who was really "first"; so, I wanted to take a look at the entire ecosystem and talk about how much credit Apple really deserves in the coming mobile 64-bit evolution.
The conversation about the topic has gotten quite muddled since Apple surprised us with the 64-bit A7, mostly because of a combination of bad choices by Qualcomm, and the unsurprising response from Samsung saying that it was working on its own 64-bit mobile processors. Qualcomm notoriously had an employee who called Apple's A7 a gimmick, saying that it would have "zero benefit" for users. Qualcomm distanced itself from the comments, and quietly reassigned the employee. That response might make you think that Qualcomm didn't agree with the statement, but really it was a public relations move because Qualcomm didn't want the backlash when it introduced its own 64-bit processors, one of which was unveiled recently.
