Still think 64 bit is stupid. My iPad Air can't keep more than 1.5 tabs loaded at a time. It is actually worse than the iPad 3 and iPhone 5 in Safari. Whatever performance benefits there are are outweighed by the pointless extra ram usage.

heh heh, you know you tabs problem is caused by dram size and has nothing to do with the 64 bits processor, right? Read up some more about processor architecture before making yourself sound really silly. :cool:)
 
I would have gladly traded 64 bit for 2gigs of memory when I had the iPhone 5s. There was no performance difference between the 5 and 5s from a speed standpoint. The paper benchmarks vs. real world performance is disappointing. This was the primary reason for not getting the new ipad's. Just knew that a device with 1gig would not last me more than a year once Apple makes the move to 2 gig.
And when 64 bit becomes a requirement most of us will be on iPhone 7s or 8.
 
Umm no. It's just bad programming. I can have multiple tabs open on my iphone 5 using google chrome without any issues. I have an iPad 4 and I have no issues with tabs in chrome.

64bit doesn't = more tabs. It's a marketing gimmick. They fix Safari and then add 64bit processor and you automatically equate 64bit with tabs. When that isn't accurate at all. They just fixed the problem in the browser.

The amount of time you lose due to constant tab reloading in Safari and reloading of already loaded apps due to paltry amount of RAM would take a lo-o-o-ot of faster 64-bit cycles to reclaim. If loading a tab saves 0.2s due to 64-bit, but reloading the tab takes 5s, you lost 4.8s of your life staring at a blank screen. Thanks to 64-bit!
 
Well apparently you do so maybe elaborate a little? Oh wait you didn't elaborate because you don't have a clue in what you're talking about. You don't even work in the IT industry do ya?

You don't understand the architecture. At all.

I agree. Usually, 64-bit doesn't do anything. But it's good to have support for it.
 
I disagree that 64bit is stupud, but RAM amount is a real problem. It is especially visible with tabs - the experience is pathetic. Also I hate that most apps "forget" their last state so fast, when you open several other apps and quickly return to it - you have to start over. This is not proper multitasking.

The question is how much money are we going to spend? Apple could have builded a model that double the ram and charge extra for it. But how many users will pony up the extra money?
 
When are people going to get that moving to 64-bit improves performance regardless of how much RAM the device has?

No it doesn't! Especially when running something in shiny new 64-bit uses enough extra RAM to make you run out of it.

Here's also one case to destroy the whole "64-bit is better than 32-bit ALWAYS" argument:
int a = 0; for (int i = 0; i<99999; i++){ a++; }
I've measured it to use about double the RAM running 64-bit.

The additional RAM usage by 64-bit apps is way overblown by some forum members here. Safari in 7.0.x has a memory leak bug, that's what causes the tab reloading and "crashes".

But, but... I saw the words "Low Memory" in some system logs, and that means there is not enough RAM!!! Sure, I don't know very much about this stuff, but I'm almost certainly right. :D

...

And have you ever thought that it's not a memory leak, but the Macrumors home page actually does take up 100 megabytes of RAM?!? Of course it loaded in 2s, but I have a pretty fast internet connection.

See my prior post about the ARMv8-64bit instruction set and it's power consumption benefits over identical apps compiled to ARMv8-32bit. The arch makes a big difference it's how Apple reduced the size of iPads, increased performance and kept the same level of battery life while running a generally more hungry OS.

I've never run out of RAM on an iPhone (leaving out times when I was hacking it). The app forgetting its state is either the developer's fault for not implementing it well or Apple's fault for forcing it to close due to a regulation, or both.
 
64bit processing is good for vmware ESXi or other virtualization applications, Microsoft exchange, Microsoft SQL, and server applications such as Micros to process credit cards.

I have my doubts you'll be running any of those on your phone.

I agree. Usually, 64-bit doesn't do anything. But it's good to have support for it.
 
This is true, but it wouldn't make a difference even there unless you were almost maxed out, and iOS didn't start closing apps to compensate.

We're talking about a difference of...maybe...50-100 meg or so overall. It's hard to say how much more memory a 64-bit app uses over a 32-bit one. It can be upwards of twice as much in worst cases, though usually it's only a scant bit more.

Yeah, but from what I've noticed Safari maxes out RAM use for people quickly.

I hate those problems too - they annoy me so much! On my iphone 5! So as these are stupid 64bit problems, I also hate Apple for secretly updating my iphone 5 to 64bit through iOS7.

Yes it does. CPU 64bit instruction sets do not operate the same as 32bit instruction sets. ARMv8-64 is the only modern instruction set in wide usage today. Every other one is 10+ years old and the newer instructions come with a massive array of speed up and efficiencies especially focused on battery life.

Not for me, but if it does, maybe they should add some kind of auto-tab-closing feature or make it more convenient to close them. I have so many tabs open from months ago that I forgot about.
 
The roadmap for 64-bit was nowhere close to Apple’s, since no one thought it was that essential," the Qualcomm insider says. "The evolution was going to be steady. Sure, it’s neat, it’s the future, but it’s not really essential for conditions now.

I believe that Apple is looking to push the envelope with what the tablet form factor can be useful for, and will soon come out with some 'pro' level iPad. If I am right, and Apple wants to make a high powered tablet device, then the sooner-then-expected move to 64 bit iOS positions Apple well for an impending iPad 'Pro' with higher performing CPUs, GPUs and RAM. I think Apple is changing the conditions, and so 64 bit is essential for them in the immediate future.

Dreaming a little bit: A huge 13" tablet with 64bit OS and 4+ GB ram doing some serious Audio, Photo and Video editing on a touch screen could be amazing...
 
I'm no computer engineer but am I right to assume that with apps going to 64bit in the future won't will eat up more memory? My fear is that with the iPad Air already reloading tabs in Safari, what is going to happen to when you start loading up 64bit apps on it next year?

It all depends on how you use your iPad. Like I said above, 64-bit apps do eat up more memory, but it's hard to predict how much exactly. Most of them only consume a little more in comparison. Like if you use your iPad for watching movies, checking out Facebook, and looking at web pages on Safari, you won't notice much difference. It'll eat up more ram, but it won't be by much. Not enough that it starts actually effecting how you use your iPad.

But if you use Pages, and Procreate, and VJay (olol), you'll start feeling cramped on 64-bit a little sooner than you would on 32-bit with just a gig of memory.

Right now, you can get by with just a gig of memory. It'd be nice to have 2, but 1 works. But like you said, it might limit the life of this generation of iDevices, and tie their staying power to the last two. This'll be especially true of the iPad, which has more developers making more complicated apps for it that are more likely to start maxing out the available ram. Unless Apple sticks with 1GB for another year, it'll make the currently brand new iPad Air and Retina Mini feel like a stepping stone devices. Kinda like the iPad 3 in a way.
 
Performance in iOS 7 on 64 bit devices is already better than performance on 32 bit devices. The OS and all first party apps ship already compiled for 64 bit operation. Again, all of this was established months ago.

Some people don't see a difference between 64bit and lot of other improvements which were implemented only for 64 bit mode in A7. Here real life sample for you: if you will need to reload page instead of using cached version of page (because 64 bit apps need more memory for code and data) it could be hundred times slower vs 32 bit version. It is not always faster - 64bit could hurt when there are not enough free RAM or CPU cache.
 
In this case "64 bits" implies Aarch64 which have several other improvements beyond bit depth.
 
How often do we see similar reports in the press?

1. Apple releases a new product.
2. Competitors gripe that it's a worthless upgrade.
3. Apple sells tons of devices.
4. Competitors rush to make their devices like Apple's.

You forgot to insert:
Know-littles write fact less columns about Apple not being able to innovate (even when the phone has a fingerprint scanner)
Know-nothing's retool last year's pieces about Steve Jobs being dead by inserting names of new Apple products.
People complain that Apple product does not make space flight possible out of the box.

The CPU cache is designed as part of the CPU. They will design it with ample cache in mind even if iOS7 may not be fully optimized yet.

They can also compress code using the algorithm they acquired a few months ago. In general, we should see overall speed up for the new devices as Apple refine iOS7 more.

Yes !

Or they could have splurged and given more RAM ...

Also, which device do you have?
