It is quite noticeable how little people actually know before posting.

People actually blame existing problems on lack of RAM

Ignorance is a good excuse for posting bollox.

Please do.

Although things seem to have improved with iOS 7.0.3, the 64-bit builds of the OS still seem to run into stability issues more frequently than their 32-bit counterparts. I still see low memory errors associated with any crashes. It could just be that the move to 64-bit applications (and associated memory pressure) is putting more stress on iOS’ memory management routines, which in turn exposes some weaknesses. The iPad Air crashed a couple of times on me (3 times total during the past week), but no where near as much as earlier devices running iOS 7.0.1.

1gb on its own normally shouldn't have been an issue, but the 64-bit processor chews up ram more aggressively, possibly causing the random crashes people have experienced.
 
Its not teh 64-bit CPU that take up the ram, it's the 64-bit software.

There was a similar issue on Windows XP when they released XP 64-bit. Machines with 1-2GB suddenly needed 3-4 to just just as well due to 64-bit applications and OS requiring more memory. Windows has worked much of those bugs out with Vista, and then 7 and now 8.

OS X didn't have the issue as much as the 32-64 bit hybrid system it had worked differently and didn't require as much in the way of memory usage. They were also not trying to just take a current code base(XP) and recompile it as 64bit(XP64).

Thank you. A well researched piece of work which explains the comments.

It does surprise me and does not fit with what I believed I knew. So much to learn, I wonder who, if anyone, I can get to review this. Young Mr Hotz would get to the bottom of this in no time but sadly he is no longer interested. I wonder if I can interest anyone else.

I have very limited knowledge and a 20 - 30% increase in memory for 64bit apps makes no sense to me.

My first thoughts are that it is 32 bit apps being poorly recompiled that is causing the problem, in which case Apple would address that rather than just throw more RAM at it but I really do need more information. I will see if I can get it.
 
Dude, it's an internet message board. A place where everyone knows nothing but thinks they are an expert. Do yourself a favor, and just pretend every post starts with "IMHO." You will be able to relax more.
Excellent although sadly I think many posters believe it's an E for Expert rather than an H for Humble.

On the iPad Air 2 RAM, I sincerely hope so as I've decided after 4+ years it's time to replace my iPad 1 so I'm hoping for the best and most future proof upgrade. I think the Air has been a big step forward.

We may never really know, since to date, only anandtech seems to have done some research on the matter, and everyone else is just parroting his findings.

Is it simply just insufficient ram, or a combination of that plus buggy software and memory leakage? We have to wait for ios8 and whether the next batch of iOS devices start sporting more ram to be certain.

I believe is that 64bit apps have much larger register too address so they can have more things loaded up at once to process which leads to more ram being used. You also get twice the amount of pointers. I don't follow understand it all but it leads to you using more ram, and intern less ram refresh and it makes everything work faster as it can be done in much larger chunks.

This however means if your starting to hit ram limit things can actual slow down or become unstable so it needs some balancing.

Hybrid systems use more ram (xp and 7 are hybrid) as they have to keep 32 and 64 bit libraries hanging around.

I hear folks quoting 10, 20 even 30 percent more memory for 64 bit ios. If that is the case then there is something majorly wrong with how IOS was coded. Typically going from 64-32 bit you get a little bit of pointer overhead but it isn't significant.

Let's say there are 100 million pointers in memory at any given time. The difference between 64 and 32 bit would be about 40 meg. A typical program would have say 200 handles and maybe 30k memory pointers? That is an extremely rough guess.
 
If the iPhone 6 is $100 more through a carrier and if it does not have 2GB of ram would = no sale! :D

Any no sale on the air 2 either.

No one can know for sure.

The first should has, so I don't have an enormous amount of faith.
 
Do you think the Ipad Air 2 will have 2GB of RAM?

Hey I have 2 tablets a Android tablet Samsung Galaxy Tab 2 7 and a Windows 8 tablet Acer Iconia W700(i5 core)

However i have NEVER bought a Ipad.

I have heard on the Ipad Air that the apps keeps on crashing and the safari keeps on reloading because of the lack of RAM(1GB).

The IOS 7.1 has fixed those issues.

I am going to wait till to buy the IPAD Air 2 with 2GB of ram and better specs and maybe a multi window feature.

But not right now because the Ipad air/mini it is over priced for a ''mid range tablet'' anyway you can get a better tablet with better specs like the Nexus 7 for under 250 pounds or one of the new ''high end'' Samsung Galaxy Tab/Note Pro tablets.

But i am wondering do you think the IPAD Air 2 will have 2GB of RAM?

What do you think everyone?
 
Most likely it will have Yes.

I have the Air(writing this on it) and the 1GB of RAM doesn't really bother me, its really a wonderful device.
 
if they will do some tricks with RAM management on iOS 8 like they did with mavericks, then there is possibility for 1GB RAM. However knowing how much there are bad coded websites, apps that 1GB RAM is too low for 2014 and later.
 
The new devices will get more RAM when Apple can do so without significantly affecting battery life.

No, no it hasn't fixed the tab reloading.

I get much fewer crashes. It's not perfect, but it's acceptable me now. Prior to iOS 7.1, it was absolutely NOT acceptable.

You think the the battery is holding back apple from putting in 2 gigs of RAM?
 
I have had no response to my requests for people to investigate so my knowledge is limited. But it still does not make sense to my very limited brain.
 
If you didn't know, more and faster RAM=better battery life.

Uh, no.

RAM is one of the biggest power consumers on a device that is always on like a phone or tablet because it must ALWAYS be powered. Even when the device is sleeping, it draws exactly the same power as when active. This is why your laptop consumes comparatively large amounts of power when sleeping as opposed to in deep sleep or hibernate where the contents of RAM are saved to disk.

If you want a device that has virtually zero sleeping power draw like the iPad does, you need to be very careful about RAM power consumption.

The screen uses so much more power than RAM that I doubt the difference between 1GB and 2GB even matters.
