Apple recently unveiled the successor of the Apple iPhone 5, the Apple iPhone 5S. The Cupertino firm boasts that the new smartphone sports the 64-bit A7 chip. However, according to a report, the new chip is only for marketing and not performance.
Extreme Tech says, “Don’t be fooled.” It explains, “None of this means the A7 won’t be faster than A6, but it does mean that the 64-bit status of the A7 is a marketing tool, not a genuine performance boost. The major reasons for adopting 64-bit architectures simply aren’t present in mobile devices. It’s not clear that a phone with 4-8GB of RAM ever makes sense given current constraints on battery life. The blend of 64- and 32-bit software means the A7 will offer strong performance in both categories (good), but won’t automatically have a clear benefit from doing so until the entire application stack has switched over. That’s not going to happen for years yet, given that iOS7 supports all iPhones going back to iPhone 4.
“For all the noted new features of the iPhone 5S, this 64-bit switch is almost entirely marketing fluff. It’s not going to be the key to the SoC’s higher performance. That’ll come from architectural improvements Apple integrates into the phone’s handling of 32-bit code for at least the next 6-12 months.”
