| Sep 12, 2013 at 4:04 | comment | added | Kris Van Bael | Most of your memory footprint will likely be UIView buffers, resources and strings. Those are hardly affected by 64 bit. So memory footprint will hardly increase. | |
| Sep 11, 2013 at 21:40 | comment | added | user28988 | It's not twice, it's orders of magnitude larger. 32-bit processors can only address 4 GB of RAM tops. 64-bit processors can address around 18 Exabytes which is 3 orders of magnitude higher. | |

| Sep 11, 2013 at 17:12 | comment | added | aglassman | I'm guessing they are taking a step in that direction to make adding more memory to later models easier. Why don't they add more memory now? It's either because the technology to pack 6-8 GB of memory on a phones board is not stable yet, or they are holding out for later models to make more money on the next generation. | |
| Sep 11, 2013 at 15:50 | comment | added | Chris.Stover | So this wasn't necessarily performance related; it has more to do with corporate/business policy and administration? My apps rarely tax the processor on my 4s but they do frequently take a vast majority of available memory. I just couldn't see a lot of short term value in the change. Seems to create more problems than benefit. | |

| Sep 11, 2013 at 15:46 | comment | added | Ramhound | @Chris.Stover - Today there isn't an advantage. Of course tomorrow an iOS application will be able to use more memory once phones have more memory. In just 5 years phone memory capacity has increase by at least 200%. If the trend continues we could see 6GB-8GB phones in a very short amount of time. Apple also looks forward when they do something like this. It all comes down to the fact ARM is likely going to only license 64-bit designs going forward. It really comes down to the fact the phone now has more registers which really makes it faster. The 64-bit specification is not important today. | |
