According to an article on the Hubspot website, Apple's iPhone5 has a 64-bit A7 microprocessor that has competitors quaking. Qualcomm provides microprocessors for Android phones that compete against Apple.
Hubspot quotes an alleged Qualcomm insider as saying, "The 64-bit Apple chip hit us in the gut. Not just us, but everyone, really. We were slack-jawed, and stunned, and unprepared."
The alleged insider says Apple's innovation is not so much of a threat now because most current software won't benefit. But it could make a difference in the future.
"A 64-bit processor handles more data in bigger chunks than 32-bit processors, so it can get jobs done faster," says the article.
Personal computers have had 64-bit chips for awhile, but Apple's is the first in a smartphone.
