Performance of iPhone 7 compared to older iPhones
Posted by Wesley on
iPhone 4S, 5, 5S, 6 Plus, 6S Plus, and 7 readying to run GeekBench 4
Smartphone software and hardware become more sophisticated by the year. So a new device is expected to be faster than its predecessor. But it's a balancing act of both raw performance and power consumption. The A10 Fusion chip in the iPhone 7 series has four cores - two high-performance cores and two power-efficient cores to do just that. It's supposed to be the fastest A-series chip yet while not impacting battery life. So how does it really do on performance? Apple claims up to 2 times faster for CPU and 3 times faster for GPU compared to 2 generations ago (iPhone 6 series). Let's see if that's true.
GeekBench 4 Result Details: 4S | 5 | 5S | 6+ | 6S+ | 7
GeekBench has been a standared in benchmarking CPU performance across many platforms. The 4.0.1 version that came out recently runs on iOS 9 or later, so I can only compare up to iPhone 4S. Still, you can see that iPhone 7 does indeed perform well. It is about 2.1 to 2.2 times faster than iPhone 6 Plus, and 35 to 40 percent faster than iPhone 6S Plus. We no longer have 2x performance jump like back in iPhone 5 - 5S transition, but things are in line with Apple's claim here.

Dealing with iPhone 7's missing headphone jack

The Lightning to 3.5mm headphone jack adapter bundled with iPhone 7
Given that iPhone's predecessor is iPod the digital music player, the listening experience is still a big part of the device for many people. So the removal of the 3.5mm headphone jack was bound to be controversial, despite the fact that Apple has provided many options to mitigate the inconvenience.

Primarily, the EarPod earphones bundled with iPhone 7 use Lightning connector, giving you at least one native solution. Along with that is a Lightning to 3.5mm headphone jack adapter that you can use with any other regular earphones and headphones. Because Lightning port is fully digital, the both the adapter and the earphones have DAC modules inside to provide analog audio output. Unless you must charge the phone at the same time, you're not worse off than before as long as the adapter works as intended.
On a side note, providing both a DAC-equipped earphone and an adapter resulted in sacrificing the plastic case for the earphones, likely because of costs. The case is now simply a throwaway paper packaging.
