Apple's New iPhone 5 Has 1GB of RAM

MacRumors · Sep 15, 2012, 08:11 PM

Apple announced the iPhone 5 on Wednesday. The new iPhone contains several improvements including the use of a new A6 processor from Apple. While it's been widely speculated that Apple would boost the RAM in the new iPhone, we haven't seen much in the way of confirmation.

The iPhone 4S and iPhone 4 both contain 512MB of RAM for developers to work with. Running out of RAM can cause some performance issues as existing applications or documents may have to be purged from memory from time to time.

iFans first posted confirmation that the iPhone 5 has 1GB of ram based on the part numbers listed on the A6 chip itself. After some investigation with Kyle Wiens from iFixit, we've been able to confirm their findings as well, using Samsung's own product guides.

The chart above comes from Samsung's 2012 Product Solutions Guide (PDF) which lists part numbers of various memory parts they have for sale. The iPhone 5's A6 part number lines up with the family of 8 Gigabit mobile DRAMs which translates into 1GB of RAM. The A5 part family is also listed and accurately shows 512MB of RAM (4 Gigabit).

Awesome, now, I can run more Tabs in Chrome without the white-out. I see Dual Channel... interesting; wonder the speed of that bus.

Michaelgtrusa · Sep 15, 2012, 08:12 PM

Guess who told this one. 

Caliber26 · Sep 15, 2012, 08:13 PM

Samsung's hateful ad already confirmed this for a lot of us.

premonition23 · Sep 15, 2012, 08:14 PM

I'm pretty sure most of us knew this

yusukeaoki · Sep 15, 2012, 08:15 PM

I guess I will be upgrading from my 4S

iPadPublisher · Sep 15, 2012, 08:16 PM

Nice... I'm even more eager to see how it performs, then.

Nice! This baby's going to scream!

G51989 · Sep 15, 2012, 08:20 PM

Ah, half the memory of the S3

But really, that is a nice upgrade, the iPhone REALLY needed it.

Treq · Sep 15, 2012, 08:21 PM

So, does this mean it runs faster or works better? Does this mean apps load quicker or switch faster? Does this effect me? Or is it more spec bull crap? Just curious...

Blackberryroid · Sep 15, 2012, 08:21 PM

Soon enough, you'll be able to run Windows 98 on an iPhone.

Nicky G · Sep 15, 2012, 08:22 PM

This is great. Anandtech discusses what the memory bandwidth is in his article on the subject:

Overall speed of the phone and fluidly of the os will improve. It's a big deal.

No, you wont

Windows 98 Runs on X86, not ARM.

Btw, Windows 98 will run on a 66mzh 486 with 16mb of ram and a 1MB video card.

Pretty sure an iPhone could handle it, assuming it was x86

Finally! Maybe now web pages will stop refreshing when you have more than a few tabs open

Nice. I figured that would happen. Apple always makes their products better when they update the hardware.

Nice! Can't wait to try it out!

Pretty sure if someone really cared, they could set up emulation...

I could've sworn it had already been done.
