iPad 3 to Have 1GB of RAM?

Tuesday March 6, 2012 4:21 PM PST by Arnold Kim

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.

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".

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.

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 left my parked at Wal-Mart, and I read in a book once that my brain is the most powerful computer in the world! :eek:


Well, perhaps not YOUR brain...:rolleyes: ;) :D

Only when sold in England, Scotland or Wales.

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 )



Geeks round things up, nerds are precise... ;)

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.

Wrong.

Test:

at 1024x768 - 299kb
at 2048x1536 - 664kb

You would need double the ram just to hold the graphics in memory and retain the same usability. Don't think that 1GB is really going to help that much it's just enough to account for the increase in resolution.

As an app developer if you jump to retina you're going to have a double the graphics/ram footprint.


Wrong.

What the previous poster was saying is that your RAM is not only used by graphics. let me use an example:

Some game uses 10% of the iPad 2's RAM for graphics = 51.2mb
The game also uses 5% of the iPad 2's RAM for processing tasks = 25.6mb
RAM left over (ignoring system used RAM)) = 512mb - 51.2mb - 25.5mb = 435.2mb

The same game on a Retina iPad with updaded graphics:
RAM used by graphics = 51.2mb * 4 = 204.8mb
RAM used by processing tasks would be the same = 25.6mb
RAM left over (ignoring system used RAM) = 1024mb - 204.8mb - 25.6mb = 793.6mb

As you can see, the 1gb RAM Retina iPad has more leftover RAM than the iPad 2 when using the same app with Retina graphics.

This is VERY rough but should give you an idea of what the original poster meant. I have made several assumptions but the principle still holds.

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


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.
