System Performance

System performance of the new iPhones should be again excellent given the hardware advancements on the part of the new A14 chip. Alongside iOS14, we should really see no problem with everyday tasks on the phone.

Unfortunately, our benchmark suite for iOS here is still relatively barren, and we have to mostly rely on web browser benchmarks – which isn’t all too much of an issue given that’s the heaviest and most demanding every-day workload for mobile devices.

Speedometer 2.0 - OS WebView

In Speedometer 2, the new A14 showcases a large performance boost of 30% for the new iPhone generation. This is likely both due to the clock frequency increase of the new CPUs as well as the fact that the new microarchitecture has in particular a larger amount of FP/SIMD resources available to itself.

Usually at this point we would point out that it’s an apples-to-oranges comparison to other devices in the chart, and that Apple’s Nitro JavaScript engine could simply be much superior to Google’s V8 engine, but the new release of the Apple Silicon Macs where we could finally compare Safari versus Chrome has shown very little performance discrepancy, meaning the performance here is actually due to the CPUs themselves.

Having that in mind, it means that Apple’s performance advantage over Android devices has grown even bigger this generation, with little hope for upcoming Cortex cores to catch up with such a gap.

JetStream 2 - OS Webview

JetStream 2 has heavier workloads and also make uses of WebAssembly, averaging out a smaller performance increase for the new A14 chip, but still showcasing class-leading performance amongst the competition.

WebXPRT 3 - OS WebView

WebXPRT is a browser workload that tries to mimic real-world interactions and workloads. The new iPhone 12s here actually show very little progress in terms of performance.

This small progress in WebXPRT is actually quite representative of my overall impression of responsiveness of the new iPhones: The A13 and iPhone 11 devices were already so performant and responsive that the actual speed limit for user interactions nowadays are just OS animations and just general SoC DVFS, the latter which Apple has already optimised to an ideal operation a few years back.

I would be lying if I were to say that I noticed that the new iPhone 12s are any faster than the iPhone 11 in everyday usage, but that’s simply because these are already are outstandingly fast devices.

    from what I gather, most cracked screens are from butt compression due to carrying in back pocket. spongy rubber-ish case won't stop that. Reply

    I know it's not as comfortable or sexy, but I hope you put something on when you go outside. I don't want you getting arrested! Reply

    Apple markets this as the strongest iPhone ever, this is pure BS. The back glass on my iphone12 broke in 3 days. I was putting on boots and the phone fell about 18 inches to a concrete floor. Unbelievable. Apple wants me to pay $100 to fix!!!! The fact is that the iPhone 12, from my experience, is by FAR the most fragile iPhone I've ever owned. Very unhappy that Apple won't even fix their defect. Phone didn't last 3 full days! Reply

    You dropped it on concrete ad you blame Apple? LOL.

    I shot my dog....its the guns fault. I ran a little old lady over. It's the car's fault.

    Why did you shoot your dog? Also, you're probably going to prison now. Reply

    Don’t you care about the little old lady?!? Reply

    They strictly clarify it's for the FRONT glass, most likely they saved upgrading the back glass for the next year model + glass is glass, no matter how strong it is, the wrong angle/force and you are done. Reply

    What is unbelievable is you didn't have any protection on your phone and now you're bitching about breaking it. Reply

    "The back glass on my iphone12 broke in 3 days."

    If anything, that shows you how strong the ceramic shield is, since only the front of the phone has the ceramic shield.
