With the iPhone 5s, Apple introduced the 64-bit A7 processor, completely setting a new hardware bar that shocked and surprised the entire smartphone industry. While the arrival of 64-bit processors was inevitable, no one expected Apple to beat everyone to the punch and leave rivals scrambling to keep up.
Some Apple rivals were quick to dismiss the A7 as nothing more than a gimmick, but such declarations were rooted in fear more than anything else. Truth be told, not only can 64-bit chips access more RAM, but they can also retrieve data in larger chunks. Additionally, the A7 brought with it tremendous improvements for certain tasks such as encoding and decoding video.
So, while the 64-bit architecture on the iPhone 5s may not have had an immediate impact on usability for all users, it signaled Apple’s efforts to future-proof its devices in the years ahead. And, naturally, rival manufacturers such as Samsung inevitably followed suit with 64-bit devices of their own.
