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.
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 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 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.

I find the flat edges of my iPhone 12 mini to be easier to grip on to than the curved edges of the older iPhones.FunBunny2 - Monday, November 30, 2020 - link
I was just about to post just that. could it be that short people with small hands are the only ones to complain about flat edged phones (and other things)? those for 4 edges, intelligently chamfered of course, are what give you purchased to hold on to that slippery thing.jeremyshaw - Monday, November 30, 2020 - link
I think completely flat edges work better on smaller phones. Mini, 5, 5S, 5C, etc. 4 and 4S as well. Though the 4 and 4S were "technically" flat, they did have the actual back and screen protruding enough to be a stepped approximation of a curved edge.xaneo - Saturday, December 26, 2020 - link
I'm jumping onto the flat edges bandwagon, all for it.milkywayer - Wednesday, December 2, 2020 - link
I still don't understand what makes the iPhone 12 worth ~$850 after tax compared to iPhone 11 that apples website is selling for $640~? Can someone explain?My biggest gripe with iOS is it kills my previous app pretty fast e.g. I could be watching YouTube or browsing a chrome tab but if I switch to reddit and or then whatsapp and then come back to the chrome or youtube, it'll make likely reload the entire app/page and I lose my progress.
I got tired of the small keyboard on my 2020 iphone SE and was going back and forth between picking iPhone 11 vs iPhone 12 and when I realized the 13 still has the same 4gb RAM, it was an easy decision going for the iphone 11 as both have the same display size and except for the tiny bit faster cpu which I probably wouldn't have noticed browsing chrome or reddit and the oled screen which isn't a big deal.
I couldn't justify spending almost 35-40% more for a tiny tiny upgrade.
What I would love for would be to get a bigger screen size like the pro max but apple has prices those out of my budget and most people's budgets I'd assume.

I guess very durable screen on 12 can pay for itself.Speedfriend - Sunday, December 6, 2020 - link
Your point about iOS is one of the main reasons I don't use an iPhone. I day trade and iOS suspending apps in the background means that I have switched quickly to a trading app to check prices not realising they are totally out of date.

That sounds like that particular app doesn't work properly. Apps can refresh in the background, but even if not, why would it take more than a second to update from waking a suspended app?ZGamer - Monday, December 7, 2020 - link
12 Pro models ship with 6GB ram vs 4GB.As with everything it depends on which models your looking and how your looking to buy. If looking at purchasing outright for some of the mvno carriers or prepaid service the 11 is a better deal. If looking at deals with bill pay credits and other incentives it can be very cheap to get a 12.
Sales around Black Friday had the iPhone 12 for free with qualifying trade and bill pay credits....12 Pro for $99 and 12 Pro Max for $199 if you had the right set of circumstances (new line/port-in only for AT&T and Best Buy).
In general year or year performance gains are generally pretty small, it's the two to five year old devices that can see larger performance improvements.....and a fresh battery.

@milkywayer these are some of the reasons that would lead me to pick a 12 over an 11...1. The iPhone 11 is an LCD screen instead of OLED, with a 2x Retina display and 1792‑by‑828‑pixel resolution at 326 ppi. The 12 is OLED with a 3 pixel per point for 2532-by-1170-pixel resolution at 460 ppi. The OLED allows the screen to be closer to the edge. I would think that is the biggest reason.
2. Significantly better night mode
3. Only 32% more, not 35-40
There are a bunch of other reasons to choose the 12 over the 11, but for me the change from LCD to OLED at MUCH higher pixel resolution and a more durable screen is sufficient.
That being said, I am still on my XS Max and will be waiting for the 13. There were days when I would upgrade my iPhone EVERY year (original all the way through the 4S). As the curve of improvements slowed down I went to every other year (5S, 6S Plus). Now I am on a 3 year tick and the XS Max is plenty good enough for me. I am looking forward to HOPEFULLY some kind of better optical zoom in the iPhone 13. However, if this was my tock year I'd be going for a 12 Pro Max with 256, but if I had to choose between an 11 and a 12 it would be a NO brainer, much more than last year choosing between the 11 and the XR (much more of a valid comparison because they both shared very similar screens). The screen on the 12 is on its own worth the price delta between the 12 and 11.
