There was a version of Geekbench a while ago for which you could make a good argument for that but Geekbench 5 seems to tell the same story that Spec, web tests, etc all tell. Apple's cores really do seem to be that good though they benefit from running at the clock speed they were designed for, unlike an Intel U-series which has more pipeline stages than it needs to hit its clock. And Apple also benefits from being…

Where can I see these SPEC results for Apple CPUs?

Anandtech frequently includes SPEC results in their reviews.

The iPhone 6s would have gotten 5 years of os upgrades. But, just because Apple won’t support a device with latest version of iOS, doesn’t mean that it won’t provide security patches and bug fixes. For instance, Apple released bug fix patches for iOS 9 and iOS 10 supporting phones back to 2011 last year. https://appleinsider.com/articles/19/07/22/apple-issues-ios-... As far as going into the trash. I had an old iPad…

basic html support doesn't work on earlier versions of ios safari due to the wrong decision that safari is bundled to ios. you heard safari is the new internet explorer? that's why it's impractical and unsafe to use earlier versions of ios.

I’ve “heard” a lot of things. But, my first generation iPad from 2010 could render any page that I went to. Of course it crashed all of the time because that iPad only had 256Mb of RAM.

As far as being “unsafe”, Apple was publishing patches for iOS 9 and 10 as late as the middle of last year.

But do you really want to compare Apple supporting older hardware to Android?

How are you going to have a PWA that works offline with server side rendering? The latest “Apple wants to force everyone to develop apps instead of using the web so they can get their 30% cut of mostly free apps” controversy was about offline storage expiring after 7 days. Not to mention that the same people who are buying cheap Android phones probably have limited data plans and/or low bandwidth.

By having a server worker that caches the whole site, done. Apple's decision doesn't apply to PWAs as clarified on a later update. Plus updating the browser cache every couple of days isn't a big deal, native apps get store updates almost every day.

So, no dynamic changes of the UI? We are talking about “web apps”.

Thanks! These are SPEC2006 which is already retired, but those numbers for the A13 do indeed come in the same ballpark as the last official SPEC2006 results that were published for Xeons in 2017 before retirement.

Many "web apps" are plain CRUD entry forms with fancy CSS animations.

I’ve done CRUD apps on mobile mostly for field services (technicians, deliveries, etc.) where it had to work offline. Even then you needed to navigate between screens, menus, navigate to different screens based on options chosen, client side validation, manage state on the client, etc.

You still needed UI changes.

geekbench have unreliable perfromance stats that've been favoring iphone for a looong while. check your conclusions - 90% of articles with rocking iphone performance cite geekbench.

Anandtech uses SPEC2006 and the performance gap is not much different than Geekbench: https://www.anandtech.com/show/15207/the-snapdragon-865-perf...

Still possible with service workers without having the poor browser chew a SPA framework.

How do service workers help if you can’t depend on having a network connection?

Are you really saying that it would he more performant that you have to make a round trip just to perform validation? How slow would the hardware have to be for a network round trip to be faster?

What do you iPhone users do with all of your power?

The other question to ask is why do some consumers want less for their money? Apple is making luxury goods, they're not going to drop their prices. It's like how there's recently been a bunch of articles about how phones are getting "too much" RAM and the comparison is laptops. When the question should really be, why do laptop manufacturers get away with putting 4 or 8gb of RAM in a laptop and mobile phones are catch…

I think this is comparing cheap laptops to expensive phones.
