Because 1GB of RAM is sufficient.I'm curious as to why apple would change the 5S over to a completely 64bit architecture and then only include 1 gig of RAM. Why would they do that? Is there any performance benefit? Thoughts?
I think it's because Apple has bigger plans for the A chip line. Maybe future laptop and desktop implementations.
Still to hard for ARM chip emulating current x86 applications. Unless you want some short of Windows RT thing on Mac...
That's why Apple is not going to put ARM in a notebook.
Why else create an 64-Bit processor where the benefits for mobile devices are minimal but would have huge potential for laptop\desktops.
I see it has a long term play. Apple can fab an A7 chip for $20 bucks. I'm sure they're paying Intel over $100 per processor. Plus Apple is first and foremost an engineering company and they now have the in-house expertise to engineer their own arm based processors. Why else create an 64-Bit processor where the benefits for mobile devices are minimal but would have huge potential for laptop\desktops. I'm not saying the changeover is coming anytime soon but Apple took a big step to go that direction by going 64 bit.
Not long ago people said Apple would never switch over from PowerPC chips.
Apple in super stingy on their RAM for some reason, they say they don't need as bad but that is complete BS in my mind.
this is why anything below 4S force closes all the time and the Ipad 1 which is only a few years old is basically a paperweight now...
What was said in the first reply is true too, but there is a performance boost as well. It's a myth that the only benefit to 64bit is to have more than 4 gigs of RAM.
Running a 64 Bit OS will let you run 64 bit programs AND utilize more than 4GB of RAM, if you have more that 4GB installed.
You don't really get a performance boost otherwise - the performance boost comes from the increased availability of memory made possible by using the 64 Bit OS.
Both things are wrong.Running a 64 Bit OS will let you run 64 bit programs AND utilize more than 4GB of RAM, if you have more that 4GB installed.
Ability to use 4GB RAM and more is not the only one of the 64 bits advantages...
Both things are wrong.
The 32-Bit OS X kernel and therefore the iOS 32-Bit kernel supports > 4 GB RAM and 64-Bit applications.
OK then would you mind enlightening me with some of these other benefits of having a 64 Bit OS?

Is this system you speak of actually "utilizing" more than 4GB? I know you can physically install more than 4GB regardless of 32 Bit or 64 Bit - but is it actually addressing any memory over 4GB?

Because 1GB of RAM is sufficient.
As i know/ heard that:
1.)It has more register which can handle large memory areas simultaneously.
2.)Higher bandwidth from more channels.
3.)Performance gain on applications which handle large data arrays.
4.)64-bit ABI allows the generation of better code than the 32-bit ABI (by passing parameters on registers instead of on the stack, for instance).
Why would 64-bit be needed for 2 GB of RAM?To force you to upgrade to this year's models, which surely will have 2+GB of RAM.

Lolz... You can't be serious.
Yes, it IS sufficient - if you don't want to have more than one tab in Safari open.
Again: lol.
