"I know there's a lot of noise because Apple did [64-bit] on their A7," said Anand Chandrasekher, senior vice president and chief marketing officer at Qualcomm, in an interview. "I think they are doing a marketing gimmick. There's zero benefit a consumer gets from that."
Chandrasekher notes that while 64-bit allows for more memory addressability the iPhone 5s only has 1GB.
"Predominantly... you need it for memory addressability beyond 4GB. That's it. You don't really need it for performance, and the kinds of applications that 64-bit get used in mostly are large, server-class applications," said Chandrasekher.
Despite the comments, Qualcomm says it will eventually move to a 64-bit processor due to benefits from engineering, chip design and OSes standpoints.
