i mentioned this on twitter awhile ago already, but figured this was worth noting here as well.

It's been in plain sight since the beginning of february when bgr posted their exclusive photos of debug output from an ipad 3 development unit. The (full) last line says:

ipad-3-3.jpg


vm_page_bootstrap: 244276 free pages and 8396 wired pages

so, just do some simple math:

244,276 (pages) x 4,000 bytes (size of a page) = 977,104,000 bytes = 977mb

iPad 3 to Have 1GB of RAM?




1gb.jpg



Based on debug screenshots originally posted by BGR, ChronicWire believes the iPad 3 (or iPad HD) being announced tomorrow will have 1GB of RAM total.

This belief is based on some calculations based on the vm_page_bootstrap number, which yields a number close to 1GB of RAM.

The Verge had previously suggested that the new iPad would have more RAM, but didn't specify the amount. The iPad 2 presently has 512MB of RAM.

It's only natural, I mean, 512 MB won't cut it and it would be a waste of the new processor if you don't have enough memory to 'catch' up with it.

With a retina display, its more important to have a larger amount of RAM. Applications are going to need to load higher resolution artwork into memory.

Saw this too, made me look at the BGR photos again. Was this the photo set that led us to believe iPad 3 would have a quad-core CPU? Because I don't see it -- there are four "[NAND] Found Chip ID" lines, but wouldn't those be for NAND flash memory?

Kinda late in the game, I'm just wondering if that's where the quad-core rumor came from in the first place (meaning - there isn't one).

I think you're right. The first iPad had 256 of RAM, the second on had 512 and the third one 1Gb. It looks like they're doubling it this time

Looking good, think its good that apple is doing this to make sure the retina display works properly. But the ARM part number from this debug image is the A5X leaked part number

Wow! It's amazing the amount of crap you can decipher form a bunch of effing gibberish.

And you call yourself geeks; a page is 4096 bytes, not 4000.

244,276+8396 (pages) x 4,096 bytes (size of a page) = 1,034,944,512 ( 987 MB )

It's not an improvement if it's not a help. It's not an upgrade if you don't' notice the difference. It's not aspirational if it's just a number

Too bad that Apple never reveals the amount of ram in their iPad devices. We'll have to wait for a third party tear down to know for sure.

I have the feeling Apple might say something along the lines of "we've doubled the RAM" at tomorrow's keynote. And maybe also claims of "five times the graphics power", "four times the screen resolution", and perhaps "up to ten times the download speed".

The vast majority of crashes on my iPad are from out of memory situations, some websites will not open at all because of their complexity. The beauty of iOS ( and OSX before it ) was in not being noticed.

With 4x the pixels (Retina) compared to iPad 1/2 the "relative" usable Ram will be back to the iPad 1's meager 256MB, won't it? Wonder if that will be as noticeable on that new iPad as on the first one in everyday use...

Forget stuff?

With 4x the resolution and only 2x the memory, won't the iPad be forgetting stuff and losing track of information? I can hardly remember where I parked at Wal-Mart, and I read in a book once that said my brain is the most powerful computer in the world! :eek:

Not that it desperately needs it, but competition dictates that it does. My Samsung Galaxy tab 7.0 plus has 1GB of ram and it's nearing or past six months old already.
